Abstract:
Storage and marketing of camel milk in arid lands of Kenya is hampered by lack of cold storage facilities. This problem can be alleviated by using storage structures incorporating evaporative cooling whose performance depends on climatic conditions. The objective of this work was to develop an artificial neural network (ANN) to predict cooled milk temperature and cooling efficiency of a locally fabricated cooler. Data were obtained from the cooler which was tested under various experimental conditions. Using some of the experimental data for training, a three-layer feed-forward ANN model based on back propagation Levenberg-Marquardt algorithm was developed using the Neural Network Toolbox for MATLAB®. The optimal model had a 4-4-2 structure with sigmoid transfer function in both layers. The inputs of the model were ambient dry bulb temperature, wet bulb temperature, wind speed and temperature of drip water, whereas the outputs were cooled milk temperature and cooling efficiency. The experimental data set (n=165) was randomly divided into training (75%) and testing (25%) sub-sets. The performance of the ANN predictions was evaluated by comparing the predicted and experimental results. The predictions agreed well with experimental values with mean squared error of 10.2, mean relative error of 4.02% and correlation coefficients in the range of 0.86-0.93. This study reveals that, as an alternative to conventional modelling techniques, the ANN approach can be used successfully for predicting the performance of locally fabricated camel milk storage structures incorporating evaporative cooling in arid pastoral areas of Kenya. The model can be used as a design tool to estimate the sizing and performance of future coolers, as it allows the prediction of the performance of hypothetical coolers designed without a need for time demanding experimentation. This can aid in up-scaling the technology.

Abstract The metrological characteristics such as the temperature and relative humidity of the cooled air in solar evaporative coolers in the form of an umbrella or awning are experimentally investigated in the work. Hygroscopic material was used for evaporative cooling. The results are compared with the data obtained from the waterproof material. They allow us to conclude that solar evaporative cooling is promising as an ecologically pure method for cooling air in open areas under canopies.

Abstract: With rising global temperatures leading to an increase in average temperatures throughout the year making people living in areas with high power outages very busy and difficult. As a modern cooling system that combines Coolers and Airconditioners does not work in the inverter for energy-saving purposes which makes them useless thus during high temperature hours. Therefore, in terms of combating the problem with portability, savings and cost-effectiveness in the concept of another climate it uses TEC while using the grid and re-charging. Although it is common knowledge that the efficiency of TEC cooperation is low compared to the air-cooled air cooler used today but with advanced production techniques and forced delivery of cold liquid that increase effective device cooling and humidity control using humidity. suction and capillary tube as a heat sink to reduce heat in the hot sink instead of air fin to reduce the surrounding heat radiation. Basically in this study we tried to increase the performance coefficient of Peltier Module using various techniques. The module also does not save energy, so over time we will not be able to use many or two or three and we need to create a cooling effect. So we keep everything in mind using the right module to achieve the goal and make it a mass production model. Keywords: Fans, Forced Convection, Peltier Module, TEC (Thermo-Electric Cooling) etc.

Abstract:
Currently, internal combustion engines have become widespread as sources of mechanical energy in many areas of human activity. It is the internal combustion engines that were and remain the most widespread in transport, where, as a rule, strict requirements are put forward for the mass-dimensional characteristics of the engines and the power plant as a whole. In order to meet these requirements, there is a constant increase in the level of forcing of the engines. For diesel engines, the most common technical measure that provides an increase in the level of engine forcing with almost unchanged weight and dimensional characteristics is an increase in supercharging pressure. However, as a result of air compression, its temperature increases, which is proportional to the degree of increase in air pressure in the compressor. An increase in air temperature causes a decrease in the mass charge of the cylinders, and therefore, a significant deterioration in the fuel combustion process. It also causes an increase in the level of maximum temperatures of the cycle, which in turn causes an increase in thermal loads and the rate of formation of nitrogen oxides in diesel cylinders. The above determines the urgency of the tasks of implementing effective charge air coolers in modern high-pressure transport diesel engines. This technical problem can be solved using air or liquid coolers. The article considers a liquid cooler, because compared to an air cooler, it can be made more compact, allows to achieve a much smaller length and volume of the intake tract, as well as to simplify the layout of the intake tract as part of the power plant as a whole, which is a priority for diesel engines. The article considers the influence of the design parameters of the supercharged air cooler on its overall characteristics and the hydraulic resistance of the supercharged air flowing through the cooler. Thus, the article provides data indicating the possibility of making a compact, highly efficient supercharged air cooler while maintaining its hydraulic resistance at an acceptable level by choosing rational parameters.

Abstract:
Thirty dairy processing plants were surveyed to determine if the psychrotrophic nature of Yersinia influenced its environmental niche within the plants. Three hundred forty-seven samples obtained from 30 dairy processing plants were tested for the presence of Yersinia spp. Ten (33.3%) plants had one or more positive sites. A total of 20 of the 347 (5.8%) sites tested were positive for one or more species of Yersinia. Yersinia enterocolitica was present at 85% (17/20) of the positive sites. It was identified by itself on 15 occasions and twice with other species of Yersinia. Other species identified included Yersinia ruckeri in 3 of the 20 positive samples (15%); Yersinia kristensenii and Yersinia frederiksenii both in 1 of the 20 (5%) positive samples. Ten of the 20 (50%) positive samples were obtained from coolers and entrances to freezers. Yersinia-positive cooler/freezer sites were obtained from 9 of the 10 positive plants. The remaining 10 Yersinia-positive sites were from raw milk receiving areas (4/10) and drains around machinery (6/10), including an ice maker, a case washer, two holding tanks, one filler machine and a packaging area. These results reinforce both the psychrotrophic nature of Yersinia and the evidence that raw milk can be a primary source of the organism. Our findings show that sanitation schemes need to be developed for coolers and freezers to prohibit the colonization and proliferation of Yersinia within these areas.

Abstract:
This study was conducted to investigate if passive cooling technologies have been implemented in commercially supplied new residential areas in Bangkok and to observe if there were significant differences in the land surface temperature (LST) compared to old residential areas. Values of LST were compared among 62 residential areas that differed in completion year. The mean LST for the most recent residential areas completed in 2013 or later was significantly less than that for the other older categories, suggesting that passive cooling effects were significantly better functioning in the new residential areas. A roof treatment on old buildings in a public housing project was still quantitatively effective after 8 years. This suggested the possibility of a deteriorated cooling function in the older categories among the residential areas. The possibility of deterioration was quantitatively investigated. The results stressed the importance of the periodic maintenance of passive cooling functions. As an extension of precise basic studies, this is the first study to quantify the passive cooling effects on commercially supplied residential areas. In terms of spatial extent, this residential area–scale study bridges precise analyses of single buildings/materials and regional observations, mainly relying on satellite data. The study results can aid in the mitigation and prevention of the urban heat island phenomenon. Doi: 10.28991/ESJ-2022-06-06-08 Full Text: PDF

Abstract:
Mobile intertidal gastropods can employ behavioural thermoregulation to mitigate thermal stress, which may include retreating under boulders when emersed. However, little is known about how gastropod occupancy of under-boulder habitats is associated with any variations in substrate temperature that exist under boulders. Thermal imagery was used to measure the temperature of boulder lower surfaces and investigate how three snail species were associated at low tide with the maximum and average temperatures underneath grey siltstone and quartzite. Lower boulder surfaces had heterogeneous temperatures, with grey siltstone having temperature gradients and quartzite temperature showing mosaics. Temperature differences between the hottest and coolest gradient or mosaic locations were >5 °C; thus there was a range of temperatures that snails could interact with. All three snail species occupied cooler parts of temperature mosaics or gradients, avoiding the hottest areas. Stronger associations were detected on the hotter grey siltstone and for the more-thermally sensitive Nerita atramentosa and Diloma concameratum. Even though snails were associated with cooler areas, some individuals were still exposed to extreme substratum heat (>50 °C). These results suggest that gastropod thermoregulatory behaviour is far more complex than simply retreating underneath boulders at low tide, as there is also a range of under-boulder temperatures that they interact with. Untangling interactions between intertidal gastropods and heterogenous substrate temperatures is important given rocky seashores already represent a thermally-variable and potentially-stressful habitat, which may be exacerbated further given predictions of warming temperatures associated with climate change.

Abstract:
In developing countries about 40 % of the food-waste is due to post-harvest losses, such as improper storage. The Zeer-pot is an evaporative cooler, which cools the inside by convective heat transfer, and can be used to keep fruits and vegetables fresh longer. This is typically convenient in hot rural areas without access to electricity and is more efficient in non-humid areas. This study will investigate if there is a correlation between the temperature decrease inside the pot and the wind velocity, how the efficiency of the Zeer-pot is affected by hanging it in the air to additionally expose the underside to the airflow and also how the efficiency is affected from glazing of the inner pot, to prevent the food from getting damaged from high humidity. It will also consider the feasibility of combining the Zeer-pot with a solar dryer, also to improve its efficiency. The evaporation is increased by higher wind velocity due to forced convection. A solar dryer can create an airflow when the heated air rises along the surface of the solar collector and creates a temperature difference between the upper and the lower part. A design for a solar dryer that could be appropriately integrated with a Zeer-pot to achieve a greater airflow around it is modelled in CAD and presented. The tests on the pots took place in a climate chamber where the ambient temperature was controllable. In the climate chamber a fan and a dehumidifier was installed in order to create wanted conditions. One pot was tested only for wind velocities and the other only for the cases of the pot hanging in the air and being glazed on the inside. A reference case was designed and tested for the second pot in order to compare the glazed and hanging pot in the same conditions. The relative humidity was not controllable in this setup, and thereof a way to compare these results was to calculate the final temperature the pot achieved relative to the lowest possible theoretical temperature, the wet bulb temperature. For the first pot an almost linear correlation between the time it took to reach the final temperature depending on the wind velocities could be observed, apart from two values. A rather nice coherent curve, also apart from two values, was found for how close to the wet bulb temperature the final temperature was depending on the wind velocity. For the second pot the cooling capacity was enhanced for both the hanging construction and the glazed pot. For the hanging pot this was expected, but for the glazed one it was not. If a solar dryer is combined with the Zeer-pot, a wind velocity around 3-3.5 m/s is guaranteed to improve the Zeer-pots cooling capacity. A lower wind velocity could probably make a large difference too, but the experiments in this study is insufficient to make any conclusions.
I utvecklingsländer beror cirka 40 % av matavfallet på förluster efter skörd, till exempel felaktig förvaring. En Zeer-pot är en evaporativ kylare som kyls med hjälp av konvektion och kan användas för att öka livslängden på frukter och grönsaker. Den är användbar i områden utan tillgång till elektricitet där klimatet är varmt och behovet för kylning är stort. Kyleffekten förbättras i ett klimat med låg luftfuktighet. Denna studie kommer att undersöka om det finns ett samband, mellan temperatursänkningen och vindhastigheten. Ett sätt att förbättra kyleffekten skulle kunna vara att konstruera någon form av stöd för att göra det möjligt för krukan att hänga i luften, detta för att även undersidan ska utsättas för luftflödet. För att inte låta fukten som skapas vid evaporationen komma in i innerkrukan där maten förvaras kan innersidan glaseras. Hur mycket dessa justeringar kommer att påverka kylkapaciteten undersöks också i denna studie. Krukan kyls med hjälp av evaporation av vatten och denna ökar vid en högre vindhastighet på grund av påtvingad konvektion. Ett sätt att skapa ett större luftflöde runt krukan är att integrera en soltork med den så kallade Zeer-poten. Soltorken skapar ett luftflöde då en temperaturskillnad mellan den övre och den undre delen får värmen att stiga upp från ytan av solfångaren. En hypotetisk modell av en lämplig soltork modelleras i CAD och presenteras. För att se en korrelation för hur ökade vindhastigheter påverkar temperatursänkningen i grader och hur fort sluttemperaturen uppnås gjordes tester på samma kruka i så i övrigt konstanta förhållanden som praktiskt var möjligt. Testen för de olika krukorna ägde rum i en klimatkammare där luftens temperatur gick att kontrollera. En fläkt och en avfuktare var installerade. Den ena krukan testades för fallet med olika vindhastigheter och den andra för den upphängda krukan och för glaseringen på insidan. Ett referensfall gjordes även för att jämföra den andra krukans två fall separat. Den relativa fuktigheten gick inte att kontrollera i klimat-kammaren och därav fick resultaten jämföras genom en framräknad procentsats. Procentsatsen visade hur långt testets sluttemperatur hade sjunkit i förhållande till den våta temperaturen. En nästan linjär korrelation, med undantag för två värden, mellan tiden det tog att nå sluttemperaturen i förhållande till vindhastigheten kunde observeras. Ett tydligt samband, också undantaget från två värden, kunde observeras mellan den våta temperaturen och den uppnådda temperaturen för olika hastigheter. För den andra krukan ökade kylkapaciteten för både den hängande konstruktionen samt den glaserade krukan. Det var väntat för den hängande konstruktionen, men inte för den glaserade. Om en soltork kombineras med Zeer-poten i syfte att märkbart förbättra dess kylkapacitet, skulle ett luftflöde med en vindhastighet kring 3-3,5 m/s garanterat fungera. Lägre vindhastigheter lär även de kunna påverka krukan nästan lika mycket, men tyvärr är resultaten från experimenten inte tillräckliga för att dra några slutsatser om detta.

Abstract:
Historically the boreal forest has experienced major changes, and it remains a highly dynamic biome today. During cold phases of Quaternary climate cycles, forests were virtually absent from Alaska, and since the postglacial re-establishment of forests ca 13,000 years ago, there have been periods of both relative stability and rapid change (Chapter 5). Today, the Alaskan boreal forest appears to be on the brink of further significant change in composition and function triggered by recent changes that include climatic warming (Chapter 4). In this chapter, we summarize the major conclusions from earlier chapters as a basis for anticipating future trends. Alaska warmed rapidly at the end of the last glacial period, ca 15,000–13,000 years ago. Broadly speaking, climate was warmest and driest in the late glacial and early Holocene; subsequently, moisture increased, and the climate gradually cooled. These changes were associated with shifts in vegetation dominance from deciduous woodland and shrubland to white spruce and then to black spruce. The establishment of stands of fire-prone black spruce over large areas of the boreal forest 5000–6000 years ago is linked to an apparent increase in fire frequency, despite the climatic trend to cooler and moister conditions. This suggests that long-term features of the Holocene fire regime are more strongly driven by vegetation characteristics than directly by climate (Chapter 5). White spruce forests show decreased growth in response to recent warming, because warming-induced drought stress is more limiting to growth than is temperature per se (Chapters 5, 11). If these environmental controls persist, projections suggest that continued climate warming will lead to zero net annual growth and perhaps the movement of white spruce to cooler upland forest sites before the end of the twenty-first century. At the southern limit of the Alaskan boreal forest, spruce bark beetle outbreaks have decimated extensive areas of spruce forest, because warmer temperatures have reduced tree resistance to bark beetles and shortened the life cycle of the beetle from two years to one, shifting the tree-beetle interaction in favor of the insect (Chapter 9).

<i>Abstract</i>.—We deployed archival temperature loggers on juvenile and adult coho salmon <i>Oncorhynchus kisutch </i>and steelhead (anadromous rainbow trout) <i>O. mykiss </i>over both the freshwater and marine portions of their lifecycle in order to study their movements and thermal preferences. Beginning in 2003, loggers were deployed on juvenile coho salmon and juvenile and adult steelhead in a small central California coastal stream. A tag recovery from a coho salmon indicates the fish experienced variable temperatures on a daily to weekly basis in the marine environment (mean 13.3°C, range 10–18°C). Tags recovered from steelhead indicate use of a cooler, more stable, thermal habitat window in the marine environment (mean 11.0°C, range 8–14°C), often with little fluctuation over a period of weeks to months, and most thermal changes occurring at the seasonal time scale. Comparisons of steelhead data with sea surface temperature data suggest a northern migration out of the California Current to a narrow band of habitat that fluctuates between the southern boundary of the Bering Sea and north of the 40th parallel. In the shallow freshwater environment, steelhead appeared to be at the mercy of stream temperatures. However, in the estuary, where thermally variable habitats were available, steelhead used a surprisingly broad temperature range, including entering water thought to challenge their thermal tolerances (>20°C) even when cooler waters were available. Temperature loggers recovered on a local beach and island indicate tagged fish were consumed in the estuary by warm-blooded predators. All of these data coupled with a larger number of passive integrated transponder (PIT) tags, are helping to identify discrete habitats fish are using, exact dates of ocean entry and return, and enhance our understanding of marine survival and predation. Finally, archival tags may be useful in understanding habitat use of pelagic long-migrating species like steelhead, by tracking individuals in areas where other tagging technologies are poorly suited.

Abstract:
Prior to COVID-19, densely occupied areas were already suspected of making employees sick. Post-COVID-19, there is an urgent need to improve air quality and ventilation standards shall change. However, any changes to ventilation must consider other negative consequences including energy and health and well-being impacts from thermal discomfort and exposure to pollutants. The need for moving away from traditional energy sources and to find alternate energy sources is undoubtedly one of the primary objectives for a sustainable progress to humankind. The design and construction of buildings in hot-humid climates requires high energy consumption typically for air conditioning due to higher thermal loads. A further increase in ventilation rates will have intensive impact in energy consumption and infrastructure loads. This chapter presents the performance of an innovative fully integrated smart ventilation system with low energy consumption. It is all in one ventilating and air conditioning system that provides efficient, cost-effective, and sustainable cooled fresh air for open or enclosed spaces whilst achieving thermal comfort. Based on the application, it consists of multistages that can dehumidify and cool the air to the required comfort level. The system has shown 50–60% reduction in energy consumption compared with conventional systems.

Full text
Abstract:
Nowadays, atmospheric water harvesting (AWH) became very essential to provide fresh potable water. This technique is in practice since 1900 (US661944A) by Edger S. Belden. Atmospheric water is a source of freshwater with 13000 trillion liters availability of water at any time and can be utilized in overcoming water shortage, especially in arid and rural areas. It holds up the water molecules in the form of vapors and accounts for adding 10% of all freshwater present on the earth. Mainly, the two most common methods have been used for the extraction of atmospheric water. First, the ambient air is cooled below the dew point temperature, and second in which the moisture in atmospheric air is adsorbed/absorbed using desiccant materials. Conventional vapor compression, thermoelectric cooling, dew, and fog water harvesting based systems/technologies possess some limits in terms of energy requirements, less efficiency, and high cost. However, the adsorption based AWH technology is relatively cheaper, environment friendly, and can be operated by a low-grade thermal energy source. The limited availability of commercial instruments to harvest atmospheric water using adsorbents indicates a lack of fundamental studies. The fundamental research on water adsorption, adsorption kinetics, regeneration conditions, and water collecting surface designs has not gained as much interest as required in the field of atmospheric water harvesting. In this regard, this book chapter discusses and presents the progress in the field of adsorbent materials and system designs along with the future directions to accelerate the commercialization of this technology.

Abstract:
It seems anorthosites are by far interested by geologists because they give us great information about Earth history and how it was evolved in planetary geology. Planetary geology is subject the geology of the celestial bodies such as the planets and their moons, asteroids, comets, and meteorites. It is nearly abundant in the moon. So, it seems studying of these rocks give us good information about planetary evolution and the own early time conditions. Anorthosites can be divided into few types on earth such as: Archean-age (between 4,000 to 2,500 million years ago) anorthosites, Proterozoic (2.5 billion years ago) anorthosite (also known as massif or massif-type anorthosite) – the most abundant type of anorthosite on Earth, Anorthosite xenoliths in other rocks (often granites, kimberlites, or basalts). Furthermore, Lunar anorthosites constitute the light-colored areas of the Moon’s surface and have been the subject of much research. According to the Giant-impact hypothesis the moon and earth were both originated from ejecta of a collision between the proto-Earth and a Mars-sized planetesimal, approximately 4.5 billion years ago. The geology of the Moon (lunar science) is different from Earth. The Moon has a lower gravity and it got cooled faster due to its small size.

Abstract:
Clouds are visual indicators of physical processes taking place in the atmosphere. They provide information about winds, stability, moisture content, and traveling weather systems that can be used in short-term (several hour) and long-term (24-36-hour) weather forecasts and in field assessments of weather conditions. Most clouds form when moist air is lifted and cooled. Lifting occurs when air rises over low pressure areas, is carried up inclined frontal surfaces, is carried upward by convective currents that originate at the heated ground, or flows over mountains. Clouds are classified according to their appearance (table 7.1) and the approximate altitude of their bases (table 7.2) following a simple scheme that was developed in 1803 by an English druggist, Luke Howard. This scheme can be expanded to describe certain clouds more precisely (World Meteorological Organization, 1987). The cloud types listed in table 7.1 are pictured in figure 7.1. The two basic cloud classifications are stratiform and cumuliform. Stratiform clouds form horizontal layers, with the horizontal dimension much greater than the vertical dimension. Cumuliform clouds, on the other hand, have roughly equal horizontal and vertical dimensions, giving them the appearance of a cotton ball. Stratiform clouds are given the stem name stratus, and cumuliform clouds are given the stem name cumulus.Stratiform and cumuliform clouds are assigned to one of three height classifications: high, middle, or low. High clouds are composed of ice crystals rather than water droplets and are named using the prefix cirro- (cirrocumulus or cirrostratus). Clouds at midlevels, which may be composed of either water or ice particles, are given the prefix alto- (altocumulus or altostratus). Low clouds are given no prefix (stratus or cumulus). When a stratus deck is composed of an array of individual cumulus elements or lumps, the term stratocumulus is used. Cirrus are stringy or fibrous high clouds that are neither stratiform nor cumuliform. Towering cumulus extend through low and middle levels of the atmosphere. A thunderstorm cloud, called a cumulonimbus. extends through low, middle, and high levels of the atmosphere and is accompanied by lightning and showery precipitation. Clouds that bring widespread, light precipitation but not lightning, thunder, or hail are called nimbostratus.

Abstract:
In many future subsea projects, there will be a requirement to cool various fluid streams, either multi-phase or single phase. To meet this need, FMC Kongsberg Subsea AS (FMC) has undertaken a project to develop a practical and robust subsea cooler. The cooler is passive in that heat is transferred to the surrounding sea water by natural convection only. Because of the subsea application, the cooler must have a special geometry to meet requirements for modularization and easy installation/removal. The passive nature of the cooler means that the flow rate of the seawater coolant is not an independent variable, but is directly linked to the cooler geometry. Developing a design method for such coolers requires detailed knowledge of the important heat transfer parameters, to an accuracy far in excess of that normally required for industrial cooler design. This problem has been approached on several levels, including an extensive literature search, theoretical studies, and model testing. One of the first observations was that little research had been done previously on this type of cooler. Much information is available for various pieces of the problem, but it became clear that designing the cooler would require significant development work. Based on the knowledge gained during the initial theoretical studies, a theory for calculating cooler performance presuming one dimensional external coolant flow has been developed. While it is clear that the actual external flow is three-dimensional, the simplified theory gives important insights into how the various design parameters affect cooler performance. To fill in the gaps in theoretical knowledge, a series of model tests designed to quantify internal and external heat transfer coefficients for the special geometry is being proposed. The testing program covers several technical areas and has required the utilization of a number of advanced measurement techniques. For the next phase of the testing program, a complete new test facility has been constructed capable of testing coolers with cross-flows typical of ocean bottom currents. The cooler development program has provided new technology which will be used to construct robust and compact subsea coolers. Because of the emphasis on basic research, fundamental knowledge and insight of the heat transfer mechanisms governing the performance of this type of cooler are acquired. This knowledge gives FMC the capability to design and manufacture subsea coolers which are custom-made to match the exact requirements of a given application.

Full text
Abstract:
The design of a nuclear plant includes “hot” containment penetration assemblies designed to protect the containment building concrete walls from the effects of localized high temperature and degradation due to thermal cycling resulting from the process piping. Typically, a penetration assembly is jacketed by coolers inside and outside a sleeve originating at a flued head on the process pipe and penetrating the containment wall. The coolers are supplied by either chromated component cooling (CC) or raw service water. Recently, a minor leak of chromated water from the penetration coolers rendered the Class 3 safety-related CC system inoperable and was isolated. Subsequently, Non-Destructive Examination (NDE) inspections of the sleeve were conducted and significant degradation was noted. The root cause of the degradation under the jacketed cooler was due to raw service water, which was used in the cooler prior to switching to CC water. Weld repairs were subsequently performed to restore degraded areas. The coolers were also removed since the air gap could provide adequate insulation to keep the sleeve below a threshold temperature for degradation of concrete. An evaluation of past functionality was still required, however, to demonstrate that the degradation did not affect the structural integrity of the sleeve and breach containment boundary. The NDE data was processed to characterize the degradation for analysis. A novel application of ASME Section XI Non-mandatory Appendix C with a simple extension of the methodology was used in the evaluation to assist the operability determination. The paper concludes that a simple extension of the code methodology was useful in establishing plant operability.

Full text
Abstract:
In power plant locations with adequate supply of cooling water the steam from the steam turbine is condensed in a water cooled condenser. In most instances circulating water from the cooling tower is used to condense the turbine exhaust steam. In other instances once through cooling is deployed wherein water from a lake, river or sea is used to condense the turbine exhaust steam. In water challenged locations or locations where wet cooling cannot be deployed due to permitting or regulatory issues, the steam from the steam turbine is condensed in an air cooled condenser (ACC) wherein ambient air is used to cool and condense the turbine exhaust steam. In a combined cycle plant, during normal operation, the water or air cooled condenser condenses the turbine exhaust steam. During bypass operation, when the steam turbine is out of service, the high-pressure steam from the HRSG is attemperated in a pressure reducing/desuperheating (PRD) valve and then admitted into the water cooled or air cooled condenser. The bypass steam flow is substantially higher than the design turbine exhaust steam flow and the duration of bypass operation can vary from a few hours to several weeks. The requirements for admission of bypass steam into a water cooled condenser are substantially different from that for an air cooled condenser. In a water cooled condenser the bypass steam is admitted in the steam dome. The bypass steam as well as the turbine exhaust steam is condensed outside the tubes. In an air cooled condenser the bypass steam is admitted in the large diameter steam duct. The bypass, as well as the turbine exhaust steam (normal operation), is condensed inside the tubes. There are similarities and differences in the requirements for admission of bypass steam into a water cooled and air cooled condenser. The differences must be identified and addressed to ensure safe and reliable performance of the condenser.

Abstract:
The emerging Distributed Energy Resources (DER) program envisions extensive use of small to midsize turbines for on-site power production. Their output decreases substantially at warm ambient conditions when it is most needed. Therefore inlet air cooling had received much scrutiny as a way to avoid this degradation. This study examines three approaches to inlet air cooling: evaporative cooling; mechanical vapor compression refrigeration; and waste heat powered absorption refrigeration. The benefits and limitations of each process were documented. Ammonia absorption refrigeration is shown to deliver the greatest benefit to continuosly operating turbines at very favorable installed and operating cost. The most economical process identified included an ammonia refrigeration cycle integrated directly into the combustion turbine cycle. This cycle was designed and modeled, and analyzed with ambient temperature conditions for six geographic areas (Boston, Atlanta, Los Angeles, Honolulu, Phoenix, and Chicago). Annual benefits for each area are detailed.

Abstract:
Thermoelectric coolers (TECs) have become potential solutions for chip cooling applications. However, the scope of TEC applicability is limited because of poor efficiency that is largely governed by material properties. This low efficiency causes increased heat production resulting in a very narrow band in which the TEC is effective. Since TECs are cooling units composed of numerous individual cooling elements, or thermocouples, the operating efficiency can be improved by implementing distributed control of the individual couples. Distributed control is a system for allowing each couple to be powered depending on the localized heat load. Distributed control would allow for increased cooling in hot spots while minimizing excess heat generated by the TEC in areas where it is not needed. The preliminary results suggest that this type of control may be feasible, and would result in a significant increase in the TEC effectiveness. The current model considers lateral heat conduction in the chip, as well as variable control of the individual thermocouples proportional to heat load. Results indicate that a 2-fold increase in COP is possible with independently controlled couples compared to a single cooler.

Full text
Abstract:
A mathematical model is formulated in this paper for the prediction of the heat rejection rate, assuming that the total heat transfer area of the mesochannel condenser is made up of 2 different areas, corresponding to superheated vapor state and the two-phase flow state. Each of these areas is considered as an independent heat exchanger (Mamani et al., 1999). The tested mesochannel condenser, manufactured by a Romanian company for automotive air-conditioning systems, is made of aluminum, based on an extrusion process; an oven brazing process was used for the headers to tubes joints. Maximum heat rejection rate represents the criteria used in order to optimize the geometrical configuration of the condenser. This theoretical study resulted in an optimized geometrical configuration of the mesochannel condenser (Heun et al., 1996a; Heun et al., 1996b). Experimental research has been carried out using a mesochannel condenser of optimized geometrical configuration. In order to ensure a quasi-state operating regime, the air-cooled mesochannel condenser was mounted inside an air loop, having multiple regulating and control means for the following parameters: inlet air dry bulb temperature, inlet air wet bulb temperature, and inlet air flow rate. The authors of the present paper develop a comparative analysis of theoretical vs. experimental heat rejection rate and heat transfer coefficient for an ammonia air-cooled mesochannel condenser.

Abstract:
Diesel engines fulfill diverse demands in urban and rural areas throughout the world. While the advantages of compression ignition engines are superior to other internal combustion engines in torque generation and fuel efficiency, some diesel exhaust emissions pose health and environmental problems. Emission reduction techniques generally diminish one type of tailpipe gas yet often sacrifice engine performance and may even raise other emission levels. For instance, exhaust gas recirculation can reduce NOx emissions. However, the dilution of the combustion charge with hot inert exhaust gas hinders the engine’s power characteristics. To solve this problem, an EGR cooler allows the exhaust gases to be cooled prior to mixing with intake air allowing a denser cylinder charge for combustion. The effective application of cooled EGR requires a smart thermal management system. In this paper, a real time empirical and analytical model will be introduced to estimate the diesel engine’s overall performance. The simplified model considers the engine’s combustion chemistry, as well as the thermal, emissions, and rotational dynamics. Representative numerical and experimental test results are presented and discussed to validate the model. Eventually, an on-board computer controller will use this model to regulate the EGR valve’s functionality and the smart thermal system.

Abstract:
The design of total temperature probes for accurate measurements in hot, high-speed flows remains a topic of great interest in a number of engineering areas, despite a broad and deep prior literature on the subject. Prediction of error sources from convection, conduction and radiation is still an area of concern. For hot-flow conditions, the probe is normally mounted in a cooled support, leading to substantial axial conduction. Also, radiation plays a very important role in most hot, high-speed conditions. One can apply detailed computational methods for simultaneous convection, conduction and radiation heat transfer, but such approaches are not suitable for rapid, routine design studies. So, there is still a place for approximate analytic methods, and that is the subject of this paper.

The circulator is a key component in a gas-cooled nuclear power plant since it facilitates transfer of the reactor thermal energy (via the steam generator) to the electrical power conversion system. Circulator technology is well established and about 200 machines, which, in their simplest form, consist of an electrical motor driven compressor, have operated for many millions of hours worldwide in gas-cooled reactors. This paper covers the evolution of circulator design, technology and operating experience, with particular emphasis on how lessons learned over the last four decades (dominantly from the carbon dioxide cooled plants in the U.K.) are applicable to the helium cooled Modular High Temperature Gas-Cooled Reactor (MHTCR) which should see service in the U.S. at the turn of the next century. State-of-the-art technologies are covered in the areas of impeller selection, bearings, drive system, machine operation, and future trends are Identified.

Full text
Abstract:
The long-term motivation for this research is to transfer useful traits from a broad based gene pool of wild species into the narrow base of a cultivated crop in Cucumis. Our primary focus was to use polyploid prior to fertilization as a tool to overcome fertility barriers in the cross between C. melo and C. metuliferus. In conducting this research, we explored all combinations of tetraploid and diploid parents, in reciprocal combinations. Pollinations were made in both the field and greenhouse, using emasculated flowers, moneocious females, and open pollination by insect vectors, with morphological selection criteria. After observations of thousands of ovaries, we still have no definitive proof that this hybridization yielded viable embryos. The most promising results came from using tetraploid C. metuliferus, as the maternal parent in the interspecific hybridization, that set fruit were seeds contained small embryos that did not germinate. To obtain fruit set, it was important to rear plants in a cooler sunny greenhouse, as would be found in late winter/early spring. A second interspecific hybrid between wild and cultivated Cucumis, C. hystrix x C. sativus, yielded fertile progeny for the first time, while concomitantly working toward our primary goal. Two distinct treatments were necessary; 1) special plant husbandry was necessary to have the wild species produce fruit in cultivation, and 2) embryo rescue followed by chromosome doubling in vitro was required for fertility restoration. Backcrosses to crop species and resistance to nematodes are compelling areas for further work.

Abstract:
On Iceland, water enriched with carbon dioxide has been injected into the upper ocean crust since 2014 – and successfully. The carbon dioxide mineralises within a short time and is firmly bound for millions of years. However, since ocean crust only rises above sea level in a few places on Earth, researchers are currently investigating the option of injecting carbon dioxide into ocean regions where huge areas of suitable basalt crust lie at medium to great water depths. One possible advantage: In the deep sea subsurface, the carbon dioxide would either be stable as a liquid or dissolve in the seawater circulating in the rock. Due to the high pressure, both the liquid carbon dioxide and the carbon dioxide-water mixture would be heavier than seawater, making leakage from the underground unlikely. But would carbon dioxide storage in the deep sea subsurface be technically feasible and ultimately also economically viable? The research mission CDRmare provides answers – with the help of the world's first deep-sea research experiment on carbon dioxide storage on cooled flanks of the Mid-Atlantic Ridge.
