Abstract:
<p>The research study focuses on the effects of relief food aid on food production and consumption patterns of communal farmers in Chigodora Ward 15, Mutare District. The researcher adopted a descriptive research design. Data collection instruments used in this research study included questionnaires, interviews as well as published documents. Questionnaires targeted households in selected villages. The researcher used a cluster sampling strategy in selecting villages and random sampling technique was used to select households from the selected villages. Interviews targeted key informants such as the Agritex Extension Officer, Mutare Rural District Council Social Services Director, and Chitakatira Health Care leader, Ward 15 Councilor, Plan International Selection Director and The Village Heads. Key informants were selected using purposive sampling technique. The researcher found out that relief food aid beneficiaries in Chigodora Ward 15 receive maize, beans, cooking oil and porridge on a monthly basis. Plan international is the only humanitarian organization which supplies food in the community. Since the involvement of food aid agencies in Chigodora, production of indigenous crops such as finger millet, sorghum and rapoko decreased. New crops such as peas are now grown. The major factors driving the persistence of relief food are HIV and AIDS, climate change, lack of fair distribution of farming inputs, the restructuring of the agricultural system and dependency syndrome. Short term impacts of relief food aid on food production and access include impacts on local taste, promotes laziness and compromises access to local foods. Long term impacts mentioned were, overall decrease in food production, disincentives on farmers to produce and exposure to low quality and unsafe products. The suggest the government of Zimbabwe needs to adequately assist and empower communal farmers to produce enough food from their fields through modern technologies as well as providing farmers with loans for inputs such as fertilizers, pesticides and equipment to improve productivity.</p><p> </p>

Abstract:
The increasing in the world population has continuously increased the energy demand. As an effective fuel, petroleum has been serving the world to meet its energy needs. Continued use of petroleum sourced fuels is widely recognized as unsustainable because of depleting supplies and all the environmental issues around its use could be responsible for a major deficit in the future. Thus, the development of alternative energy sources, are to be welcomed. Biodiesel, as an alternative fuel, has many benefits. It is biodegradable, non-toxic and compared to petroleum-based diesel, has a more favorable combustion emission profile, such as low emissions of carbon monoxide, particulate matter and unburned hydrocarbons. In brief, these merits make biodiesel a good alternative to petroleum based fuel. The use of alternative feedstock as waste cooking oils (WCO), bovine fats and microalgae oil for biodiesel production has some advantages. It is cheaper than edible vegetable oils and it is a way to valorize a sub-product. Nevertheless, these oils has some contaminants, which can reduce the quality of biodiesel, a problem that was solved by testing different operating conditions and equipment designs for each stage of processing. The technological assessment of this process was carried out to evaluate their technical benefits, limitations and quality of final product. In this work biodiesel was produced by an alkali-catalyzed transesterification, a reaction involving the WCO feedstock and an alcohol to yield fatty acid alkyl esters (biodiesel) and glycerol. The evaluation of quality from raw materials and final biodiesel was performed according to standard EN 14214. Results show that all parameters analyzed meet the standard and legislation requirements. This evidence proves that in those operating conditions the biodiesel produced from WCO, bovine fats and microalgae can substitute petroleum-based diesel.

Abstract:
Purpose – The purpose of this paper is to examine food preparation practices of US older adults by assessing their conceptualization of food preparation methods and their routine use of food preparation methods and kitchen equipment. Design/methodology/approach – In total, 17 community-dwelling older adults used cards with names of food preparation methods and cooking equipment items to do one open sort and three closed sorts about: food preparation method classifications; food preparation method use frequency; kitchen equipment use frequency; and essential vs non-essential kitchen equipment. Descriptive statistics, cluster analysis, and qualitative thematic analysis were performed. Findings – Participants classified food preparation methods using multiple dimensions: ways to alter food, inputs, location, timing, and personal behavior. They used a wide range of food preparation methods and kitchen equipment items in routine cooking. The mean number of the 38 preparation methods sorted as used “often” was 16.5±5.0. In total, 15 of the 17 participants reported using more than 20 of the 40 equipment items “often.” The mean number of equipment items identified as “essential” was 21.5±9.3. Practical implications – Food professionals should consider access to equipment and food preparation skills and preferences when designing products and working with consumers. Addressing gaps in human and material capital may support adoption of food preparation practices. Originality/value – Food preparation method and equipment use frequency has rarely been examined from the household cook’s perspective. Using card sorts is a novel approach to examining consumer classification of an extensive list of preparation methods and kitchen equipment.

Abstract:
A monomer processing reactor is a device to process used cooking oil into new substance that can be used for other applications. In this study, used cooking oil was converted to monomer via simple reactor comprised of stirrer started with laboratory scale of 2L to 5L of monomer production. A scale up process is an important process for approaching industrial scale productions. The scale up process was increased to pilot scale before it reaches to industrial scale. The reactor is designed based on lab scale process for producing monomer from used cooking oil. The most important point of the device design is to produce larger amount of monomer compared to lab scale equipment. The device can produce 15liters of monomer per production. The monomer has the same properties and quality of monomer that were produced using laboratory equipment.

Abstract:
Biodiesels are substitute fuel sources that can be potential replacement to fossil fuels apart from being eco-friendly owing to their carbon-neutral nature. The energy originating from nature-based resources has a premium value due to its lowest environmental impact. The strategies that protect nature are grouped under a philosophy termed as ‘sustainability’. The biodiesel ought to give net energy acquire, have ecological advantages with financially serious, and producible in enormous amounts without diminishing food supplies. The proposed study examines potential of waste cooking oil as a source of bio-diesels by collecting samples of used cooking oil from the food outlets. The characteristics of producing bio-diesel from waste cooking oil are investigated from the point of view of utilizing it on a small batch mode of 5 to 10 litre. The chemistry of transesterification is investigated by adopting computational route to design a reactor and experimentally verifying the small-scale production.

Abstract:
Globally, states are obliged to prioritize quality medical care at emergency departments (EDs). Kenya is not an exception since medical care services are mainly offered in the outpatient departments. However, the quality of care in these outpatient departments has not been evaluated. The aim of this study was to investigate quality of care at EDs of public hospital in Kenya, with a focus on Bungoma County. The study evaluated the availability of infrastructure, equipment, supplies and personnel. Besides, the researcher assessed processes, protocols, and outcomes of care at the Eds in Kenya’s public hospitals. A cross-sectional study design was employed, with a sample of 10 ED in-charges and 398 patients. The participants were proportionately recruited from the EDs via probability proportional to size (PPS). Quality of the EDS was measured using the Donabedian model with structure assessed by evaluating availability of infrastructure, equipment, supplies and personnel for emergency care. Process was evaluated by measuring turnaround timelines, assessment of presence and utilization of triage systems, protocols, and guidelines. Outcomes were measured using number of admissions, deaths, left without being seen, unplanned re-attendance, and patient service experience. Data collection was based on WHO observation checklists and with the help of questionnaires. The analysis consisted of descriptive and inferential statistics. The findings revealed that infrastructure availability was 42.0% with all EDs lacking resuscitation rooms and high dependency units. Secondly, imaging rooms were in 40% of the hospitals, blood banks in 50%, and running water in 70%. Third, equipment availability was 34.7% with oxygen source, pulse oximeter, point of care ultrasound and trauma cart being available in 10%. Fourth, regular maintenance of equipment was in 52.5% of the EDs. Finally, availability of supplies for resuscitation was 52% with Supplies for airway management being the least (22%). From the study, it was apparent that trained personnel, equipment, supplies and processes such of triage systems. This has contributed to prolonged turnaround time and high re-attendance rates. There is need for provision of adequate infrastructure, equipment, personnel, and systems for emergency care in public hospitals EDs in Bungoma County to improve quality of care.

Abstract:
This work covers a reassessment of the 'Hot Break' separation problem by a mechanical engineer from outside the brewing industry. The solid-liquid separation problem was therefore investigated without prior knowledge of constraints or current practices. During the brewing of beer an unwanted, insoluble precipitate, 'trub' is formed, reported to have undesirable effects on the finished beer quality. The existing equipment, 'whirlpool' separators, designed to eliminate this 'trub' performed poorly, allowing much of the precipitate to be carried over to subsequent processes. To remedy the problem, a program to either: 1. design suitable replacement separators or; 2 • modify existing separators to enhance their performance, was pursued. To evaluate possible alternative separators determination of the relevant physical (solid, liquid) properties, measurement of the process parameters at peak production, and review of the chemical constraints was necessary. Performance of the current whirlpool separators was ascertained to establish the extent of the ~xisting problem. Existing efficiencies set a benchmark for comparison against proposed alternatives. Through exhaustiv~ literature review, consultive advice, a series of experiments and rig testing, an extensive range of separation techniques was evaluated, A review of over forty-five reports on whirlpool performance and design practices, the majority of which being the basis of doctoral dissertations, combined with the evaluation of a third whirlpool at Milton Brewery revealed whirlpools to be the most suitable and logical choice. It seemed that the inherent problems in whirlpool design stem from the haphazard approach adopted by the brewing industry. To redress this problem an exp~rimental program to optimize whirlpool tank geometry and operation was initiated. Both experimental and hardware design were fundamentally different to all previous endeavors to establish whirlpool design guidelines. A pilot plant was designed and commissioned such that direct measurement of the 'whirlpool' response independent of other secondary effects was possible. The experimental program produced · over two hundred comparative whirlpool indices over a range of geometric and operational configurations. These suggested that whirlpool performance could be optimised in shallow vessels using low inlet velocities. Finally, the need for secondary separators to be used in conjunction with whirlpool tanks would diminish with improved primary separation.

Abstract:
Nitrogen oxides control the photochemical production of ozone 03 in the lower atmosphere and influence the concentration of the hydroxyl radical HO in the troposphere. As an important member of the nitrogen oxide family, N02 plays a significant role in serving as the only known source of ozone (through photolysis) in the lower atmosphere and as sink for HO via formation of nitric acid. Therefore, accurate measurements of nitrogen dioxide are essential for the understanding of the processes that determine the distribution of tropospheric ozone and for assessing the impact of human activity on the troposphere. Although reliable and sensitive techniques for the direct measurement of nitric oxide NO have been developed, these results could not be fully applied to direct N02 measurements. The purpose of the present study was to further develop a low pressure laser-excited fluorescence technique for measuring N02 by introducing the idea of a Two-Chamber-Fluorescence-Cell. Theoretical considerations of the performance of such a cell and the flow regime within the cell were done in order to assess the optimum cell design and the conditions for optimum operation. Measurements on a provided two-chambered test cell were done to verify the theoretical predictions made. This test cell has been explored with a Nd:Y AG pumped dye laser (100mW@564nm, 30Hz) and a supplied N02 concentration of lOOppm. The theoretical results suggest that the concept of a Two-Chamber-N02- Fluorescence-Cell yields an improved sensitivity compared to present direct techniques for measuring N02 In addition, experimental results give a better understanding of how to realize the initial idea of an operating Two-Chamber-N02- Fluorescence-Cell.

Abstract:
Light can be coupled out of a waveguide to a focused point by a focusing grating coupler and has possible applications in optical data storage. The grating can be fabricated with either e-beam techniques or holographic techniques. Two design methods are demonstrated that model the focusing grating coupler with holographic optical elements. Both methods take a geometrical optics approach to designing the holographic optical elements and both methods make use of commercially available ray trace programs. The first method uses complicated non-rotationally symmetric construction optics and requires either a modified ray trace program or special user defined surfaces. The second method involves a much simpler approach which did not require any changes to an existing ray trace program and requires only rotationally symmetric elements to correct the aberrations.

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2007
The increasingly sedentary lifestyle of the past 30 years has contributed to declining health. Consequently, exercise is vital for good health maintenance. The global Health and Fitness Industry repeatedly indicates the need for optimally managed exercise with accurate information feedback. Compared to other industries, the fitness industry is lagging behind in incorporating Information Technology into its operations. On the other hand, the most current exercise equipment impose fixed-trajectory exercise on users with the dominance of static equipment designs. These exercise equipment are normally deadweight-based equipment. In deadweight-based exercise equipment, the weights generally can be changed only when the equipment is inactive. Therefore, a more novel exercise environment is required for current exercisers in the fitness industry. This thesis explores to develop a computer-controlled pneumatic dynamic resistance exercise equipment with onboard data management. This new technology optimises exercise effectiveness for users. Exercisers will have advanced diagnostic capacity, and will capture user data which can be manipulated into meaningful information for use by Health and Fitness Industry stakeholders. This thesis will explore all the key concepts about computer-controlled equipment. The key concepts to be investigated will include FX (force-displacement) control technology, pneumatic system control, fail-safe mechanics, and Graphical User Interface design. The primary aim of the project is to replicate and enhance the functionality, performance, and sensation of deadweight-based equipment. A further aim of the project is to investigate the feasibility of designing a compact retrofit-able pneumatic unit to replace the deadweights of existing standard exercise equipment. The computer control will be implemented on a "National Instruments PXI" computer featuring Data Acquisition and Control (DAQAC) capacity, and the software will be implemented using "LabVIEW 7.0', which is a graphic object-oriented computer language developed to facilitate hardware I software communications.

Abstract:
A tractor mounted three-point hitch implement was developed to extract and collect subsurface trickle irrigation laterals from the soil. Power to the implement was supplied by the tractor hydraulic system to the three-point hitch and two remote hydraulic circuits. In operation, the implement loosened the soil around the lateral, extracted the tubing from the soil, wound it on a reel assembly, and then dropped the roll of tubing at the end of the row. Draft power requirements averaged 14.5 kW (19.4 hp) and hydraulic power averaged 0.56 kW (.75 hp) when the one row implement was operated at 7.2 km/h (4.5 mph). Field capacity of the one row implement averaged 0.19 ha/hr (.47 ac/hr) when operated in 100 m (328 ft) long rows.

Abstract Besides the induction coil and workpiece, the induction generator (source of ac power) is probably the most important component of an overall induction heating system. Such equipment is typically rated in terms of its frequency and maximum output power (in kilowatts). This chapter addresses the selection of power supplies in terms of these two factors as well as the operational features of different types of sources. The six different types of power supplies for induction heating applications covered in this chapter are line-frequency supplies, frequency multipliers, motor-generators, solid-state (static) inverters, spark-gap converters, and radio-frequency power supplies. The chapter discusses the design and characteristics of each of the various types of power supplies.

Abstract An outdoor electronic equipment is under consideration. In order to attain the desired system performance and reliability, the junction temperature of all electronic components and the base plate temperature of the power supply under the worst environmental conditions must be kept below 105°C and 85°C, respectively. A system level transient analysis is performed to determine the temperatures of the internal air and the power supplies which are mounted to the internal structures of the system. The transient is caused by the daily cycle of ambient temperature and solar flux. The internal air temperature and the base plate temperature of the power supply are computed for a 24-hour period. The above thermal design limits are met with the computed internal air temperatures and flow rates.

Abstract:
When an original equipment manufacturer no longer supplies and/or supports a product then the product is considered to be obsolete. Obsolescence is a significant problem for systems whose operational and support life is much longer than the procurement lifetimes of their constituent components. Unlike high-volume, commercial products, which are quickly evolved, long field life, low-volume systems, such as aircraft may require updates of their components and technology called design refreshes to simply remain manufacturable and supportable. However these systems can’t perform design refreshes all the time due to the high nonrecurring and re-qualification costs. One approach to optimally managing this problem is to use DRP (Design Refresh Planning), which is a strategic method for scheduling design refreshes such that the life cycle cost impact of obsolescence is minimized. The planning of these design refreshes is restricted by various constraints, which need to be implemented into the DRP process. These constraints can reflect technology roadmap requirements, obsolescence management realities, logistical restrictions, budget ceilings and management policy. In this paper, constraints imposed on the DRP process are explored, classified within a taxonomy, and implemented in the planning process. A communications system design example is included.

Abstract:
Abstract The Lead-bismuth eutectic (LBE) test irradiation loop is an indispensable testing vehicle for the investigation of LBE-cooled reactor fuel. To make a water-cooled research reactor have the irradiation test capacity of LBE-cooled reactor fuel, a test irradiation loop is investigated and preliminarily designed by absorbing the design and operation experience of the domestic and international heavy liquid metal loop. Structural material corrosion, impurity blockage, polonium diffusion, and metal solidification in the loop are considered in the design process. Corresponding measures have been taken to ensure the safe operation and emergency capacity of the loop. The loop is a 1500KW facility consisting of a coolant system and auxiliary systems the other, operating in a wide temperature range of 250–480 °C, oxygen concentration 0.01–0.05 ppm. The coolant system is to remove the heat from the fuel surface due to irradiation. Auxiliary systems are for coolant chemistry control, emergency fuel cooling, polonium control, and parameter measurement. In this paper, the technological process, main design parameters, and system composition of the loop are described, and the parameters and selections of main equipment, instrument parameters are proposed. The investigation supplies a useful reference for further design of test irradiation loop systems and equipment.

Abstract:
This study describes an operation pressure and supplies flow rate of an axial cooling fan installed in high-density packaging electronic equipment. Fan performance is generally defined by their P-Q curve, specifically, a relationship between fan pressure rise (ΔP) and flow rate (Q). A compact cooling fan often operates in a high-density mounting device, which may decrease the fan performance. In this study, we focus on an obstruction near a fan, which is electronic components such as PCBs, capacitors and heat sinks, as one of a factor which decreases fan performance. We installed a perforated plate which simulated the above components near a fan and measured the P-Q curve. To investigate a relationship between a fan performance decrease and an opening position near the fan, a part of the perforated plate was closed. Closed position was changed and explored an opening condition which caused the dominant fan performance decrease. From experiments, it was found that the fan performance was decreased when flow passage in front of a fan was blocked by an obstruction. Especially, when flow passage in front of a fan hub was blocked, a dominantly reduction of fan pressure was caused. An obstruction rear a fan has no effect on a fan performance curve itself. In addition, opening conditions in front of a fan tip had a little influence on a fan pressure characteristic when there was no obstruction in front of a hub.

"Development of a Test Methodology and a Design Tool to Predict the Wear Rate of Flexible Risers Outer Sheaths Installed in I-Tubes."

Abstract:
The interface between the flexible risers and I tubes installed in floating production units is being considered by the industry as a critical region regarding wearing due to its geometric characteristics and high contact loads between the flexible risers and I-tube interface equipment. During the past few years some instances of outer sheath damage were reported by the offshore industry. Such occurrences have been responsible for the unplanned maintenance of flexible pipes and production loss. Based on this scenario, Wellstream has developed and incorporated into its regular supplies, a new model of riser interface equipment with a replaceable polymeric liner, which has been qualified through a full-scale test program and demonstrated to be adequate in protecting the flexible pipe’s outer sheaths [1]. Although the developed equipment was originally designed to allow the replacement of the polymeric liner, which acts as a sacrificial part, the planning of periodic inspections and the determination of the optimum liner thickness could not be reliably performed due to the lack of solid experimental data regarding the wear rates of the polymer pairs and the contact pressures expected for that region. As part of an internal research program, a FEA model has been developed and calibrated in order to allow the assessment of the contact pressure between the flexible pipe’s outer sheath and the I-tube interface equipment for the actual contact pressures generated by the field fatigue loads, supporting the development of a midscale test program to determine the wear rates of the polymeric materials pairs as a function of the contact pressure [2]. The determination of these two main variables allowed the definition and conception of a dedicated design tool and the generation of experimental data to the flexible riser interface equipment and its polymeric liner, increasing the reliability of the flexible risers installed in I-tubes. This paper presents a discussion regarding the contact pressures experienced by the flexible pipe sample in service, the basis for the experimental test program and the concept of the developed design tool.

Abstract:
With continued emphasis on sustainability-driven design, reverse logistics is emerging as a vital competitive supply chain strategy for many of the global high-tech manufacturing firms. Various original equipment manufacturers (OEMs) and multi-product manufacturing firms are enhancing their reverse logistics strategies in order to establish an optimal closed-loop supply chain through which they can introduce refurbished variants of their products back into the market. While a refurbished product strategy helps to mitigate environmental impact challenges as well as provide additional economic benefits, it is limited to an existing product market, possibly a subset of the existing market, and fails to commercialize/target new markets. In addition to refurbishing, the alternatives available for utilizing End-Of-Life (EOL) products are currently restricted to recycling and permanent disposal. In this work, the authors propose employing a new EOL option called “resynthesis” that utilizes existing waste from EOL products in a novel way. This is achieved through the synthesis of assemblies/subassemblies across multiple domains. The “newly” synthesized product can then be incorporated into the dynamics of a closed-loop supply chain. The proposed methodology enables OEMs to not only offer refurbished products as part of their reverse logistics strategy, but also provide them with resynthesized product concepts that can be used to expand to new/emerging markets. The proposed methodology provides a general framework that includes OEMs (manufacturers of the original product), retailers (distributors of the original product and collectors of the EOL products) and third-party firms (managers of the EOL products) as part of a closed-loop supply chain strategy. The proposed methodology is compared with the existing methodologies in the literature wherein a third-party supplies the OEM only with refurbished products and supplies products unsuitable for refurbishing to another firm(s) for recycling/disposal. A case study involving a multi-product electronics manufacturer is presented to demonstrate the feasibility of the proposed methodology.

Abstract:
California State University, Sacramento has designed and constructed a cogeneration laboratory for the instruction of students in modern electrical generation. This facility serves about 100 senior level students per year. The major components are a 75 kW gas turbine generator, a waste heat boiler and a small absorption chiller. Future plans include the addition of a 50 kW steam turbine. The analytical design of this plant is described from concept to final layout with particular emphasis on cycle analysis, selection and sizing of components and instrumentation, and the layout of the equipment. A diagram showing the entire cycle on a scaled temperature entropy plot provides an interesting graphical interpretation of the plant’s operation. While the gas turbine has a relatively low pressure ratio of 3.3:1 and thus a low thermal efficiency, the addition of the other components improves the performance significantly. An aspect of the analysis of particular interest is relating the cooling of the chiller to an equivalent work term thus enabling the determination of an overall thermal efficiency. If all of the steam were to be used for cooling the plant efficiency would improve slightly from 10% for the turbine alone; when made equivalent to other types of refrigeration the improvement is more than 6%. When all of the steam is used in the proposed steam turbine the efficiency will improve to about 17%. Using the chiller to cool inlet air to the gas turbine—thus increasing performance—is discussed at length. Student use of the laboratory is discussed briefly. While the plant is quite small and intended for laboratory use, the design analysis is applicable to similar plants which might be used in remote locations, or as stand-by or peaking power supplies.

In 2018 Design of Medical Devices Conference. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/dmd2018-6945.

Abstract:
A-priori research show that trans-tibial (TT) amputees display poor gait parameters when walking with passive mechanical ankle-foot prosthetics (AFP’s). This has large implications for the amputee populations in the developing world, who have limited access to advanced prosthetic technologies and instead rely on baseline AFP’s. Analysis of such baseline AFP’s in literature indicates that the predominant issue with these devices are their inability to adequately replicate the mechanics of a normal ankle during the stance phase of a walking gait cycle. This has shown to be a contributory cause of increased energy expenditure, as well as secondary complications such as osteoarthritis and joint deterioration. This paper presents the design and analysis of a modular low-cost ankle-joint prosthetic (AJP) that serves as an attachment to existing prosthetic feet, with the intention to improve the ankle mechanics thereof. The AJP is modelled to reproduce ankle joint mechanisms, specifically controlled relative angular flexion in the sagittal plane, using only simple mechanical elements (i.e. compression springs instead of electronics). Initial results were positive, indicating that the AJP improves the stance phase mechanics of the baseline AFP in a simulated TT amputee gait cycle. During forefoot dorsiflexion rollover, an 80%–132% (p < 0.001) increase in joint angle and a 42–56% decrease in ankle stiffness (p < 0.001 for all but one participant) is observed. Following heelstrike a 22%–77% (p < 0.001) increase in joint angle is observed. However equipment and methodology errors left the moment response of this phase unverifiable. The overall conclusion of this paper is that the introduction of the AJP to baseline AFP’s supplies evidence of improved rollover shapes, easier phase transitions, and the facilitation of footflat during mid-stance.

Full text
Abstract:
Brazed Aluminum Heat Exchangers (BAHX) are commonly used for heat transfer equipment in liquefied natural gas (LNG) services. Specific operational design parameters as well as mechanical design characteristics are critical to consider in the construction and ultimately for the operation of the unit in order to ensure a safe design and successful operation for the facility. The growth and demand for natural gas has been extensive in recent years as clean burning fuels have become more of a priority than coal plants. Due to limited natural gas supplies, many LNG facilities have been considered as a means to provide and meet the consumers’ needs for natural gas. These LNG facilities such as LNG import receiving terminals or LNG Liquefaction Plants have a need for handling cryogenic materials. In these LNG applications, BAHX are an ideal fit for this use and have many advantages as a result of being able to be designed for minimal approach temperatures as well as lower log mean temperature differences (LMTD) than other exchanger types. These parameters are key to the plant’s refrigeration and overall energy loads. Discussed and detailed in this paper will be various uses and applications for BAHX along with design considerations for their use. Details regarding materials of construction, maintenance, and other mechanical aspects will be presented that lead to a safe and reliable means for transferring heat.
