Creator:: Lajevardi, Babak
Abstract:: Worldwide, many organizations are pursuing higher energy efficiency by reducing power consumption of their processes, systems, and supporting infrastructure. The rapid growth of the information technology (IT) industry and the miniaturization of semiconductors have resulted in substantial increases in energy consumption and power density of IT equipment, and, subsequently, heat...
Resource Type:: Dissertation

Creator:: Ghazvini, Mohammad
Abstract:: A novel microscale combustor-heat exchanger (μCHX) for hydrogen storage applications is presented in this dissertation. The design of the μCHX is motivated by its application to two particular systems for automotive use- those that utilize metal hydrides (MH) and cryo-adsorbents (CA) to store hydrogen. Thermal energy needs to be supplied...
Resource Type:: Dissertation

Creator:: Brannon, Samuel T.
Abstract:: To improve the performance of solid oxide fuel cells, a secondary power cycle can be driven by the recuperation of exhaust gas heat. Microchannel recuperators are attractive for waste heat recuperation due to compact form factors which also minimize the mass of the expensive superalloys required. This paper introduces a...
Resource Type:: Masters Thesis

Creator:: Pashak, Jeffrey J.
Abstract:: A simple heat exchanger network has been studied as an example of a dynamically interactive process. The process is relatively simple, requiring only temperature measurements and flow rate manipulations. Equations are presented for the design of a physical process having a specified steady-state Relative Gain Array and specified dynamic characteristics....
Resource Type:: Masters Thesis

Creator:: Ranasinghe, Jatila
Abstract:: The second law of thermodynamics, through the exergy concept, allows us to quantify and rationally cost the consumption of exergy (irreversibility) used to drive the heat exchange process and the effluent losses of exergy in a heat exchanger For systems with a network of heat exchangers, the exergy concept recognizes...

Creator:: Pawar, Supriya V.
Abstract:: The need for clean and renewable fuel such as hydrogen is driven by a growing worldwide population and increasing air pollution from fossil fuels. One of the major barriers for the use of hydrogen in automotive industry is the storage of hydrogen. Physisorption is the most promising storage technique due...
Resource Type:: Masters Thesis

Creator:: Yih, James S.
Abstract:: Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...
Resource Type:: Masters Thesis

Creator:: Ingram-Goble, Robbie
Abstract:: The performance of a combined Stirling-ORC power cycle is evaluated, and an integrated microchannel heat exchanger is designed as an annular cold-side heat rejector for a free piston Stirling engine. Reasonable designs for a combined cycle can increased power output efficiency by 3 - 9% compared to that of a...
