Design of a microstructured liquid-liquid separator utilizing a capillary pressure gradient

Creator:: Zoebelein, Conor M.
Abstract:: Continuous liquid-liquid two-phase separation is needed in microfluidic devices. Due to the small characteristic lengths of microreactors, phenomena such as mass transport via molecular diffusion occur within seconds. Typically, discrete slugs of an extract are created within microchannels for high specific interfacial area to achieve intensified mass transfer. A challenge...

Energy Analysis of Novel Data Center Cooling Technology : Evaporative Cooling System Operation and Microchannel Heat Exchanger Manufacturing

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...

Numerical design of a high-flux microchannel solar receiver

Creator:: Rymal, Charles
Abstract:: This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

Microchannel extraction of Te⁴⁺ from a stream of CdTe via MIBK in supported liquid membrane

Creator:: Liburdy, Heather Johnson
Abstract:: A new technique is developed to recover elemental tellurium (Te) from cadmium telluride (CdTe) which is abundantly available in photovoltaic semiconductor waste. The method is based on microchannel fluid flow with the use of a supported liquid membrane (SLM) between the donor (feed) and acceptor (strip) channels. A predictive theoretical...

Design of a single lamina for a microchannel dialyzer with a focus on bubble removal

Creator:: Mohammadi, Mahshid
Abstract:: A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...

Oxidation of hydrocarbon in a carbon nanotube supported corona discharge in micoreactor : oxidation of ethylene

Creator:: Alanazi, Yousef M.
Abstract:: Population growth driven sustainability issues, including the food resource issue, are pressing problems in need of attention. The goal of the present thesis is to examine the ability of an electric non-thermal plasma based microreactor to destroy ethylene, a known plant hormone responsible for losses in the range of 20%...

Determining the dimensional requirements of a reliable compression sealing method for use in microchannel hemodialysers

Creator:: Ward, Dustin K.
Abstract:: Almost 600,000 people in the United States were treated for End Stage Renal Disease in 2010. A majority of those people received hemodialysis from central medical facilities. It has been reported a better treatment option for these patients would be realized if the patients had more frequent hemodialysis treatments. A...

Development of an economical high temperature microchannel recuperator for solid oxide fuel cells

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...

Enhancement and modeling of cryogenic solid-state hydrogen storage systems with a novel microchannel thermal management device

Creator:: Loeb, Christopher S.
Abstract:: Compact storage systems demonstrating increased hydrogen storage capacity are the key to advancing the growth of the hydrogen economy throughout the world and reducing the global dependence on fossil fuels for transportation. The use of highly porous adsorbent materials for reversible hydrogen storage is a promising pathway towards achieving storage...

Laser keyhole welding for microlaminating a high-temperature microchannel array

Creator:: Lajevardi, Babak
Abstract:: Microchannel process technology (MPT) components are chemical unit operations which exploit highly-parallel arrays of microchannels to process large fluid volumes for portable and distributed applications. Microchannel heat exchangers (MCHXs) have demonstrated 3 to 5 times higher heat fluxes when compared to conventional heat exchangers resulting in proportionate reductions in size...
