Abstract:
The objective of this work was to develop an acoustic method for evaluating energy consumption during the jet mill operation on the basis of the new generalized physical laws of material dispersion at it destruction. Theoretical explanation is given to the problem of energy consumption diminish in the mode of fine grinding. Dependences between the product dispersion and critical energy density in the course of destruction are described. The acoustic-emissive parameters of dispersion of the samples loaded by compression and results of acoustic estimation of the jet grinding are considered. Interrelation between the gas-jet mill performance and parameters impacting on the energy consumption are analyzed. Grounds are given for using a criterion of extremal control of the working process for maintaining maximal performance. An acoustic size effect of dispersion is formulated by the analogy with dynamic size effect of destruction (DSE). A new approach to evaluation of energy consumed by the jet mill is developed from positions of unity of nature and mechanism of the loaded body destruction with community of manifestation of physical laws of acoustic emission and effects of new surface formation on the destroyed particles. Leading role in the methodology of energy consumption evaluation is given to the coefficient gN (J/imp) of transformation of the consumed energy into acoustic radiation at optimal mode of the mill operations (at maximum performance), which is calculated as a ratio of the reduced work (energy) to the acoustic signal counts in the grinding zone. Current energy consumption ЕDt (J) for period Dt (s) of work is calculated with taking into account coefficient gN (J/imp) and average (for the interval Dt) acoustic activity (imp/s). It is possible to maintain minimum energy consumption at the jet grinding by the snap-acting control of jets loading up to the level of the measured acoustic activity in the grinding zone, at which a “conditionally permanent” value of coefficient gN can be achieved. The results of acoustic evaluation of effective surface energy at optimal grinding mode correspond to the range of estimation gs in the regularity of the DSE destruction. This fact confirms validity of the dispersion theory (including the acoustic size effect) use for evaluating current energy consumption in the course of the jet mill operation.

Abstract:
Introduction. Theoretical and empirical research into rock blasting proved that detonation wave propagation results in the development of destruction and pre-destruction zones around the explosive cavity. In the destruction zone, rock crushes. In the pre-destruction zone, stresses set up by the detonation wave are concentrated on rock mass structure defects, giving rise to new micro defects and the development of the existing ones. Rock fracturing and cavitation increase, lowering its strength properties; this is called rock pre-destruction. There are works devoted to the qualitative analysis of rock in the pre-destruction zone, but the problem requires elaboration to offer possibilities for practical application. Research aims to quantify rock mass pre-destruction to use the parameters of rock blasting by borehole charges under opencast mining in engineering calculations. Methods of research. To assess the degree of rock mass pre-destruction at a distance from the charge axis, a pre-destruction intensity coefficient is used. The destruction zone radius is determined by a well-known method. In the destruction zone, the value of the pre-destruction intensity coefficient is higher than one, i. e. there is discontinuity of the rock mass. Beyond the destruction zone, there is a pre-destruction zone where the value of the pre-destruction intensity coefficient is less than one. The pre-destruction zone boundary is at distances of the order of 200–250 charge radii. The pre-destruction intensity coefficient of a particular zone attained after all charges have been fired is determined by summing the pre-destruction intensity coefficient from every charge. According to the energy approach, rock strength can be assessed by the value of the specific drilling energy intensity. In order to determine the reduction value of the specific drilling energy intensity in a particular zone, it is essential to know the drilling specific energy capacity of this zone in the natural state, the pre-destruction intensity coefficient attained after a large-scale blast of borehole charges, and specific drilling energy intensity of completely disintegrated rock. The effect made by another borehole charge explosion on the rock mass is weaker due to its pre-destruction by previous blasts. So we propose the impact multiplicity coefficient that reflects the accumulation of pre-destruction in a particular zone under the sequence blasting of borehole charges. Results. The expected value of the specific drilling energy intensity has been calculated for the individual arbitrarily spaced wells within the pre-destruction zone of a particular rock mass zone. The calculation results were compared with the practical values measured during blasting preparation in the preset rock mass zone. Conclusions. The findings of this study have made it possible to quantify the impact of explosions on rock mass pre-destruction. The developed technique makes it possible to predict the value of drilling energy intensity in the pre-destruction zone and, as a result, establish the required specific energy intensity of detonation and hence the consumption of explosives. Thus, it becomes possible to reduce the consumption of explosives under the existing blasting scheme at the enterprise and model other charge initiation types to select the least expensive one.

Abstract:
The crushing equipment is characterized by a significant energy-consuming system during the crushing workflow. The current trend in the development of such processes puts forward requirements for the development of new or improvement of existing energy-saving equipment. The essence of the solution to the problem in this work is determined by using resonant modes, which are inherently the most effective. The practical implementation of the resonance mode has been achieved taking into account the conditions for the interaction of the resonant vibration crusher with the material at the stages of its destruction. The degree of the stress-strain state of the material is taken into account, which was a prerequisite for identifying the potential for the development of a vibration load. Composed equations of motion based on a substantiated discrete-continuous model of a vibration crusher and processing material. An approach is applied to determine the stepwise destruction of the material with the determination of the required degree of energy. This methodological approach made it possible to reveal the nature of the process of material destruction, where energy costs at the stages of crack formation, their development and final destruction are taken into account. It was revealed that the greatest energy consumption during the operation of crushers goes into the kinetic energy of the crushing plates and the potential energy of deformation of the springs. The proposed model is common for any design of a vibration machine and its operating modes. The stable resonance mode has made it possible to significantly reduce the energy consumption for the course of the technological process of material grinding. The results obtained are used to improve the calculation methods for vibratory jaw and cone crushers that implement the corresponding energy-saving stable zones of the working process.

Abstract:
This experimental study determines the energetic and exergetic performances of an air conditioner using blend of R22/R600a (60:40 by mass) for different volume fractions (0.1 %, 0.2 %, 0.3 %, and, 0.4 %) of TiO2 nanoparticles dispersed into mineral oil (MO). Energetic and exergetic parameters investigated in this experiment including power consumption, cooling effect, discharge pressure and temperature, coefficient of performance (COP), exergy destruction (irreversibility), irreversibility in the component, sustainability index (SI) and exergy efficiency at different operating conditions. The k-type thermocouples and pressure gauge were used to measure the temperature and pressure at different locations of the air conditioner. Thermodynamic characteristics of the refrigerant were collected using REFPROP 7. Results showed that the lowest power consumption and total exergy destruction were observed in the system with 0.4% volume fraction of TiO2 nanoparticles charge in the TiO2/MO lubricant with refrigerant blend; these values of energy consumption and total exergy destruction were 12.76 % and 7.5 % respectively, which is lower than R22/Polyol ester (POE) lubricant. The COP for the blend was increased by 6.5% to 8.3% compared to R22 and with nano-lubricant COP for the blend was increased by 17.9% to 19.9% compared to R22/POE. The air conditioner using blend charge with 0.4% TiO2/MO lubricant has the maximum COP and exergy efficiency among the selected nano-lubricants. These values of COP and exergy efficiency were 19.9 % and 35.07 % respectively, greater than that of R22/POE. Again, compressor discharge temperature was found to be decreased with the introduction of nano-lubricants compared to the original system, and the expectancy of compressor life may be extended with TiO2/MO nano-lubricant. Among the components, the compressor was found to be maximum exergy destroyer (at 60 %), followed by the condenser (at 25.4 %) and evaporator (at 13.3 %). Overall, the study found that refrigerant blend with nano-lubricant minimised the energy consumption and exergy destruction and the system operated safely with nano-lubricant without any system modification.

Abstract:
This paper examines the huge destruction that has taken place in some cities of Iraq due to the terrorist acts in recent years that led to the destruction of many buildings. It examines some of the factors that encourage the use of residues of these buildings in reconstruction processes, especially the sustainability factor, so that some residues of these buildings can be used as substitutes for natural building materials and find a difference in terms of energy consumption in the case of using natural building materials and again in the case of using the proposed alternatives. In this study, three alternatives were used: 10% recycled fine aggregates (RFA), 100% RFA, and crushed clay brick aggregate (CCBA) to produce recycled coarse aggregates. The results obtained through the use of building information modeling (BIM) technology were compared with the actual consumption of the building in the case of reconstruction using natural building materials. The simulation results were comparable to real data. They were analyzed in terms of the energy consumption life cycle and annual carbon emissions for each alternative. The best alternative was selected from the results obtained from BIM. The best alternative was found in the use of CCBA in the production of concrete roofs and floors. His final model is that the energy consumption was five times lower than the original unit, while the results of carbon emissions were equal as for the electricity consumption decreased from 23,500 kW/h to less than 23,000 kW/h.

Abstract:
The aim of the work is to assess the factors that determine the effectiveness of devices used at different stages of ore processing. The nature of the destruction at each stage is determined by different parameters, therefore, it is so important to search for information factors that allow evaluating the response of mineral raw materials to external influences at the stages of ore preparation. The research methodology is based on the analysis of energy and power factors, which can be correlated both with the loading device and with the body being destroyed. Force factors characterize the response of a material to damaging effects, for example, the limiting amount of resistance to deformation is estimated by the force at which the destruction occurred. The results of the analysis of the role of energy and power factors are given on the example of a selfgrinding mill, a centrifugal crusher, and others. The effectiveness of the self-grinding mill is determined by the ratio of energy and power parameters in the processes of ore lumps kinetic energy conversion into the energy of elastic and breaking strains of the crushable (and crushing) material. It is shown that 88 "Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal". No. 1. 2020 ISSN 0536-1028 the efficiency of centrifugal crushers is ensured by the high intensity of collisions of a multitude of particles, which initially possess excess kinetic energy. In devices such as a roller-press or a cone inertial crusher, the final phase of destruction is associated with volumetric deformation of the layer. This means that the final stages of destruction are completely determined by the structural and strength characteristics of the feedstock and its particle size distribution. The field of application of the presented results are technologies in which the liberation of minerals during ore destruction is considered as a process of structure transformation based on the principles of rational ore preparation. The properties of ores, energy and force factors are important informational parameters of the analysis and selection of methods of destruction during the liberation of minerals. Examples of successful and unsuccessful use of a roller press as a device for reducing the energy consumption for ore preparation are explained within the framework of ideas about the relationship between energy and power factors.

Abstract:
Crushing machines are part of the charge departments of blast-furnace and steel-making shops of metallurgical enterprises. One of the main indicator of the crushing process is its energy efficiency. It is determined by the mass of crushed material when consuming a unit of electricity. The article considers various methods of crushing brittle materials and the design of crushing machines for their implementation. The analysis of the crushers has shown that impact crushers are the most energy-efficient. However, due to a significant drawback (the yield of a suitable product is very small), they are practically not used in the metallurgical industry, in which high requirements are imposed on the finished product fractional composition. In the metallurgical industry, compression crushers are widely used with approximately the same specific energy intensity, that is, with the same energy consumption for the destruction of a unit volume of material of equal strength. Compression fracture is the most energy intensive crushing method known. In single-roll crushers, a piece of material is fed into the gap between a roll and a solid, stationary plate. During the operation a complex stress state is generated in the destructed material. Compressive forces act on a piece of crushed material, causing normal compressive stresses in it, and an internal torque, causing shear stresses. This is achieved by the reduction in energy on crushing by 20 – 30 % in comparison with crushers operating in compression (all other things are equal). The authors describe the design of a crusher, in which the destruction of the processed material occurs due to the forces acting on the crushed piece in one plane towards each other. In this case, only shear stresses arise in the processed piece. The use of crushers, in which the destruction of the processed material occurs due to generation of only tangential stresses in a piece, can reduce the energy consumption per unit of finished product by almost a half. The design of such crushers is a promising direction in the development of machines intended for crushing.

The MIT community has embarked on an initiative to the reduce energy consumption and in accordance with the Kyoto Protocol. This thesis seeks to further expand our understanding of how the MIT campus consumes energy and with that knowledge be able to recommend methods of reducing energy consumption by minimizing and even eliminating careless energy use. The largest energy consuming building per square foot, Building 39, was selected and analyzed in detail. This thesis proves the unnecessarily high airflows and irresponsible fan use are the source of Building 39's wasteful consumption of energy. Research revealed that the recirculating fans drew the most energy and were continuously running on full power. If the fans were turned down during off peak times the consumption of electricity could be decreased by as much as approximately 26% and save the Institute $250,000 a year in electrical costs.

Abstract:
With the widespread adoption of smart meters in buildings, an unprecedented amount of high- resolution energy data is released, which provides opportunities to understand building consumption patterns. Accordingly, research efforts have employed data analytics and machine learning methods for the segmentation of consumers based on their load profiles, which help utilities and energy providers for customized/personalized targeting for energy programs. However, building energy segmentation methodologies may present oversimplified representations of load shapes, which do not properly capture the realistic energy consumption patterns, in terms of temporal shapes and magnitude. In this thesis, we introduce a clustering technique that is capable of preserving both temporal patterns and total consumption of load shapes from customers’ energy data. The proposed approach first overpopulates clusters as the initial stage to preserve the accuracy and merges the similar ones to reduce redundancy in the second stage by integrating time-series similarity techniques. For such a purpose, different time-series similarity measures based on Dynamic Time Warping (DTW) are employed. Furthermore, evaluations of different unsupervised clustering methods such as k-means, hierarchical clustering, fuzzy c-means, and self-organizing map were presented on building load shape portfolios, and their performance were quantitatively and qualitatively compared. The evaluation was carried out on real energy data of ~250 households. The comparative assessment (both qualitatively and quantitatively) demonstrated the applicability of the proposed approach compared to benchmark techniques for power time-series clustering of household load shapes. The contribution of this thesis is to: (1) present a comparative assessment of clustering techniques on household electricity load shapes and highlighting the inadequacy of conventional validation indices for choosing the cluster number and (2) propose a two-stage clustering approach to improve the representation of temporal patterns and magnitude of household load shapes.
M.S.
With the unprecedented amount of data collected by smart meters, we have opportunities to systematically analyze the energy consumption patterns of households. Specifically, through using data analytics methods, one could cluster a large number of energy patterns (collected on a daily basis) into a number of representative groups, which could reveal actionable patterns for electric utilities for energy planning. However, commonly used clustering approaches may not properly show the variation of energy patterns or energy volume of customers at a neighborhood scale. Therefore, in this thesis, we introduced a clustering approach to improve the cluster representation by preserving the temporal shapes and energy volume of daily profiles (i.e., the energy data of a household collected during 1 day). In the first part of the study, we evaluated several well-known clustering techniques and validation indices in the literature and showed that they do not necessarily work well for this domain-specific problem. As a result, in the second part, we introduced a two-stage clustering technique to extract the typical energy consumption patterns of households. Different visualization and quantified metrics are shown for the comparison and applicability of the methods. A case-study on several datasets comprising more than 250 households was considered for evaluation. The findings show that datasets with more than thousands of observations can be clustered into 10-50 groups through the introduced two-stage approach, while reasonably maintaining the energy patterns and energy volume of individual profiles.

Abstract:
Based on the impressions given by information gathered within the frames of this project, there most definitely exists a need and interest for a product that increases the employees’ awareness of their company’s energy usage. Interactive Institute should consider the prerequisites satisfactory and follow through with their project in creating a product that fulfills this need. The chance to create a powerful, yet economically defendable, product is great considering that the product would include features not previously available to the market at an attractive price level. With limited manpower within the company together with a wish of turning this project into a marketable product, cooperating with Exido/eZE Systems would be the most fruitful solution. Using their Input/Output device and already ‐built communications system gives Interactive Institute the possibility to focus mainly on the Graphical User Interface/Web portal and the technical involvement would only need to cover signal handling from existing meters to the I/O box as well as integrating the Exido software system with the new customer web portal. This cooperation would also grant Interactive Institute an important head start compared to other manufacturers possibly in the beginning of launching similar projects. Thereby the chances of hitting the market with a unique product, before any competition exists, increase significantly. If involving an external part is not an option due to internal reasons, developing the meter from earlier projects further and replacing the previously used WLAN module with a LAN module (or possibly simply adding LAN capability) would be the second most efficient solution in terms of manpower efficiency and not making the product more expensive than necessary.

In forecasting long-term primary energy consumption, we work with four different Shared Socioeconomic Pathway Scenarios (SSPs) developed for the Intergovernmental Panel on Climate Change (IPCC) framework, assuming different challenges to adaptation and mitigation. We find that in all scenarios, China, the United States and India will be the largest energy consumers, while highly growing countries will also significantly contribute to energy use. We observe for most scenarios a sharp increase in global energy consumption, followed by a levelling-out and a decrease towards the second half of the century. The reasons behind this pattern are not only slower population growth, but also infrastructure saturation and increased total factor productivity. This means, as countries move towards more knowledge based societies, and higher energy efficiency, their primary energy usage is likely to decrease as a result. Global primary energy consumption is expected however to increase significantly in the coming decades, thus increasing the pressure on policy makers to cope with the questions of energy security and greenhouse gas mitigation at the same time.

Abstract:
Electrical consumption for data centers is on the rise as more and more of them are being built. Data center owners and operators are looking for methods to reduce energy consumption and electrical costs. One method of reducing facility costs for a chilled water plant is by adding an economizer. Most studies concerning economizer systems are largely conducted by looking at energy alone since the primary focus has reducing electrical costs. However, little research has been published that examines exergy destruction for these types of systems based on varying outdoor air conditions by locale. The purpose of this study has been to develop energy and exergy-based models of each of the most common economizer systems. In this paper, a normal chiller plant without an economizer and a chiller plant with an indirect wet-side economizer (the most common type of economizer system) are compared. A method for simulating a mechanical cooling system is provided and results show outdoor conditions influence facility energy consumption and exergy destruction.

Abstract:
Major interests in the automotive industry include the use of alternative fuels and reduced fuel usage to address fuel supply security concerns and regulatory requirements. The majority of previous internal combustion engine (ICE) control strategies consider only the First Law of Thermodynamics (FLT). However, FLT is not able to distinguish losses in work potential due to irreversibilities, e.g., up to 25% of fuel exergy may be lost to irreversibilities. To account for these losses, the Second Law of Thermodynamics (SLT) is applicable. The SLT is used to identify the quality of an energy source via availability since not all the energy in a particular energy source is available to produce work; therefore optimal control that includes availability may be another path toward reduced fuel use. Herein, Model Predictive Control (MPC) is developed for both FLT and SLT approaches where fuel consumption is minimized in the former and availability destruction in the latter. Additionally, both include minimization of load tracking error. The controls are evaluated in the simulation of a single cylinder naturally aspirated compression ignition engine that is fueled with either 20% biodiesel and 80% diesel blend or diesel only. Control simulations at a constant engine speed and changing load profile show that the SLT approach results in higher SLT efficiency, reduced specific fuel consumption, and decreased NOx emissions. Further, compared to use of diesel only, use of the biodiesel blend resulted in less SLT efficiency, higher specific fuel consumption, and lower NOx emissions.

Abstract:
Abstract In this work, steam generation was studied using natural gas or rumen as energy sources in a slaughter plant that sacrifices 7500 cattle per month, with consumption 0.5749 kg/s of saturated steam at 624 kPa. For a slaughtered cow, 10.5 kg of rumen can be obtained after being dried outdoors; for its final disposal, the slaughter plant bears the costs of USD 7.2 per ton of rumen. In the study, exergy and exergoeconomic performances were compared by generating steam with a natural gas boiler with the steam generation with a rumen boiler. From this, combustion analysis, energy efficiency, exergy destruction, exergy efficiency, exergy destruction costs, and generating 1 kg of steam from the two boilers were evaluated. The study results showed that the generation of steam with rumen is less efficient than with natural gas since it presents the exergy destruction of 1175.9 kW and exergy efficiency of 26.83%. While the generation of steam with rumen boiler was obtained, with exergy destruction of 1419.9 kW and exergy efficiency of 23.29%. Exergy destruction cost and the cost of generating 1 kg of steam using rumen were $/h 7821 and 0.0073 $/kg, respectively. Although the generation of steam with natural gas present the exergy destruction cost of 26285 $/h and the cost of generating steam of 0.021 $/kg, this indicators are higher using natural gas as a fuel that with rumen pellets.

Abstract:
Abstract Gas condensate stabilization is a common process in gas refineries and petrochemical industries. This process is energy-consuming since it uses distillation columns and furnaces to separate different cuts from the condensate feed. This study aims to improve the performance of the gas condensate stabilization unit in a large petrochemical company in terms of energy efficiency and loss prevention. The case under investigation is the gas condensate stabilization unit in the Nouri Petrochemical Company, treating 568 t/h of raw condensate feed. This plant includes two distillation columns, two furnaces, pumps, heat exchangers, and air coolers. A hybrid energy and exergy analysis is conducted in this study. First, the validation of the simulation phase is performed, and a parametric sensitivity analysis is conducted to explore the effects of various parameters, such as operating temperature and pressure, on the process performance. After that, the most influential variables are identified using thermodynamic analyses for optimization and design purposes. An optimization method is employed to attain the maximum production improvement and exergy efficiency. The exergy analysis shows 187.4 MW total exergy destruction in the plant; furnaces account for 79% of the total exergy destruction. According to the sensitivity analysis results, the energy consumption of the process could be reduced by 33.7 MW; this is an 18% reduction in the plant's energy consumption. The optimal process conditions outperform the current and design states (4.6% improvement in exergy efficiency). The fuel gas consumption is reduced by 2.1 t/h, leading to a reduction of 128 t/d CO2 emissions.

Abstract:
Abstract Environmentally friendly and effective power systems have been receiving increased investigation due to the aim of addressing global warming, energy expansion, and economic growth. Gas turbine cycles are perceived as a useful technology that has advanced power capacity. In this research, a gas turbine cycle has been proposed and developed from a simple and regenerative gas turbine cycle to enhance performance and reduce Specific fuel consumption. The impact of specific factors regarding the proposed gas turbine cycle on thermal efficiency, net output, specific fuel consumption, and exergy destruction, have been inspected. The assessments of the pertinent parameters were performed based on conventional thermodynamic energy and exergy analysis. The results obtained indicate that the peak temperature of the Proposed Gas Turbine Cycle increased considerably without affecting fuel consumption. The results show that at Pressure Ratio (rp = 6) the performance of the Proposed Gas Turbine Cycle is much better than Single Gas Turbine Cycle but the total exergy destruction of Proposed Gas Turbine Cycle higher than the SGTC.

Abstract:
The HLRP method is combined with optimization techniques to determine the best combination of a tri-generation system composed of a hybrid fuel cell system and alternative energy sources such as wind and solar energy. Solar thermal and photovoltaic systems with short term storage are used in this study. A small commercial site in Southern Europe is investigated. The HLRP method is based on using the ratio of the thermal load to the required power as the scaling parameter to analyze a hybrid fuel cell based tri-generation system in terms of performance parameters. The performance parameters, energy utilization factor, carbon dioxide and exergy destruction per total energy load, are reported in a series of graphs. The HLRP analysis is based on ideal performance of the power producing devices and practical performance parameters of all heat transfer devices. The alternative energy systems included in this analysis include state-of-the art performance measures. The previous publications on the HLRP method have focused on its development with short examples that illustrate how it operates as an effective, initial screening tool and limited cost factors. In this paper the application of the HLRP method as an early screening tool to determine the general outline of an efficient, total energy solution is detailed. The tool will be used to compare different solutions based on the fuel consumption (energy utilization factor), carbon dioxide production, exergy destruction and costs. The tradeoffs of reducing costs or increasing carbon dioxide production are illustrated. The solutions are based on a process using regression curves of the generalized graphs. The correlation coefficient for these regression relationships is greater than 0.996. In addition, refinement of the HLRP technique that reports carbon dioxide production and exergy destruction in terms of total energy rather than thermal loads has been adopted. Combining the generalized performance of the fuel consuming components with renewable energy sources leads to a solution based on balancing cost, minimizing fuel consumption or carbon dioxide production.

Abstract:
The Building Energy Data Book (2009) [1] shows that commercial and residential buildings in the U.S. consume 39.9% of the primary energy and contribute 39% of the total CO2 emissions. In the operation of buildings, 41.8% of building energy consumption is provided for building cooling, heating, domestic hot water, and ventilation for commercial buildings, while in residential buildings, this percentage increases to 58%. In energy system analysis, the energy approach is the traditional method of assessing the way energy is used in an operation. However, an energy balance provides no information on the degradation of energy or resources during a process. The concept of exergy combines the first law and second law of thermodynamics. The exergy analysis clearly quantifies the energy quality match between the supply and demand sides, and also addresses the exergy destruction (entropy generation) in each component. In this paper, a solar thermal driven absorption cooling system was analyzed for providing cooling to a building, the Intelligent Workplace South Zone at Carnegie Mellon University. The system includes a 52 m2 parabolic trough solar collector, and a 16 kW (4 tons) two-stage lithium bromide absorption chiller. The energy model and newly developed two-stage lithium bromide absorption chiller are programmed and integrated in Engineering Equation Solver (EES). The temperature, enthalpy, entropy, mass flow rate, and mass fraction of lithium bromide in the solar absorption system were presented in steady state operation. The exergy destruction in each component is calculated. The exergy destructions for the solar collector, generator, absorber, and heat exchangers were significantly higher than those in evaporator, condenser and expansion valves, the overall energy and exegetic efficiency were also calculated.

Abstract:
Abstract Electronic cooling represents a major portion of a Data Centers energy consumption, thus efficient thermal management dramatically impacts energy savings. This work proposes reducing the energy consumption associated with server air-cooling by vectoring (tilting) the main upward tile flow using adjacent synthetic jets. The particular fluid dynamics generated by synthetic jets allows controlling the angle at which the tile flow emanates, directing the cooling air toward areas with higher cooling demand. Three-dimensional simulations were performed using k–ε standard turbulence model with the commercial software Ansys Fluent. In order to quantify and localize the inefficiencies of the system, we estimated the Exergy Destruction distribution in the cold aisle and servers. In previous studies, this technique proved successful in finding optimum operation conditions in Data Center cooling. As opposed to a base case without flow control, the adjacent synthetic jets directed the incoming fluid to areas with higher cooling demand, thus saving energy by avoiding over-provisioning air into servers operating under normal demand. The decrease in the overall Exergy Destruction demonstrated that vectoring improves the system’s global energy efficiency.

Abstract:
Ship subsystems and mission modules perform energy conversion during their operation resulting in a combination of electricity consumption, heat generation and mechanical work. These multi-physics subsystems often have opportunities for performing an energy storage role during their operation cycle. The kinetic energy stored in the rotating mass of a generator set or the electrical energy stored in a railgun pulse forming network are but two examples of energy storage aboard warships. Treating each subsystem as a disconnected entity reduces the potential for exploiting their inherent interactions and results in over-designed shipboard systems with excessive weight and volume. Exergy - the amount of energy available for performing useful work - provides a path for exploiting multi-physics energy flows. Utilizing the Second Law of Thermodynamics, by modeling and minimizing exergy destruction, a recent study, showed that exergy control increased the overall efficiency by 18% over traditional optimization techniques when applied to a terrestrial HVAC application. In this paper a notional, multi-physics ship power system is developed that explicitly captures the exergy flows. Particular attention is given to exergy destruction phenomena. Simulation of the system illustrates operational characteristics with greatest impact on exergy destruction highlighting areas for applying optimal, exergy-based control schemes. This approach will allow ship designers to minimize the size and weight of installed power generation, energy storage and thermal management systems, enabling the affordable implementation of advanced weapons and sensors.

Abstract:
We know petroleum hydrocarbons degrade in soil via chemical, physical, and biological pathways. Innovative remediation technologies enhance degradation by one or more pathways e.g., in-situ and ex-situ. The typical goal of degradation is to achieve the applicable regulatory criteria. Some, State Agencies, e.g., Louisiana, Texas, require oil total petroleum hydrocarbon (TPH) contamination levels be reduced to ≤10,000 mg/kg. However, other agencies, e.g., New Mexico and California, require oil contamination levels reduced to <1,000 mg/kg. Even 100 mg/kg is not uncommon, e.g., Los Angeles, County, CA. Microbial populations and substrate availability often limit biodegradation at petroleum hydrocarbon levels <1,000 mg/kg. Conventional laboratory biodegradation microcosm studies require an inordinate amount of time to evaluate petroleum hydrocarbon treatability (as measured by loss of analyte) and even more time to optimize treatment parameters that facilitate or improve kinetics (lower half-life values). Two studies discussed here demonstrate the utility of oxygen consumption respirometry in evaluating oil impacted soil treatability. In the first study, oxygen consumption rates were measured after a 1-week incubation period at varying TPH levels (5800 and 1000 mg/kg), carbon:nitrogen (C:N) ratios (100:1 and 25:1), and manure content (0, 0.5, 1.0 and 5.0 percent). Results showed TPH and C:N ratios significant at < 1 percent level and manure significant at < 5 percent level. The second study, a longer-term study (132 day) showed oxygen consumption resulted from degradation of gasoline range (GRO) and diesel range (DRO) fractions of TPH. These studies provide a means of evaluating treatability of low concentrations of petroleum hydrocarbon and a method for assessing treatment options that are passive in nature, but less destructive to the environment.
