An economic and environmental assessment model for microchannel device manufacturing

Creator:: Gao, Qi
Abstract:: A key application of microchannel process technology (MPT) is its implementation in heat exchanger devices, since a larger surface contact area can be realized than in conventional approaches, thus achieving high heat transfer efficiency. To justify high volume production of configurations validated as prototypes, and to select from among the...

Single- and multi-functional arrayed microchannel fluidic devices

Creator:: Fisher, Luke W.
Abstract:: Novel fluidic devices that utilize an array of microchannels to achieve their designed purpose are discussed. Examples of devices include: fuel reforming using Microreactors, chip cooling using microchannel heat sinks, and microchannel devices used for biological applications. The devices that have directly contributed to this research include: a microchannel water...

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 self-registration features for the assembly of a microchannel hemodialyser

Creator:: Porter, Spencer D.
Abstract:: More than 1.2 million people worldwide require regular hemodialysis therapy to treat end stage renal failure. In the United States alone, there are 300,000 patients and the National Kidney Foundation predicts that this number will double in the next 10 years. Currently most dialysis patients receive treatment at a dialysis...

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...

Adhesive microlamination protocol for low-temperature microchannel arrays

Creator:: Paulraj, Prawin
Abstract:: A new adhesive bonding method is introduced for microlamination architectures, for producing low-temperature microchannel arrays in a wide variety of metals. Sheet metal embossing and chemical etching processes have been used to produce sealing bosses and flow features, resulting in approximately 50% fewer laminae over traditional methods. These lamina designs...

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...

An investigation of multiphase flow in complex microchannel geometries for hemodialysis systems using residence time distribution analysis

Creator:: Coblyn, Matthew Y.
Abstract:: There are approximately 2.2 million cases of End-stage Renal Disease (ESRD) worldwide and current hemodialysis treatment is costly and ultimately insufficient compared to kidney transplantation. There is a strong need to arrive at a better solution for treating ESRD. Microchannel-based hemodialysis is one proposed option, already shown to have improved...

Design, fabrication and testing of a high temperature ceramic microreactor for synthesizing silicon nitride nanoparticles

Creator:: Jain, Kartavya
Abstract:: An alumina microreactor was designed and fabricated to study the synthesis of nanosized silicon nitride powder via the ammonolysis of SiO vapor at temperatures ranging from 1300°C to 1400°C. It is the first high temperature ceramic microreactor capable of operating at temperatures upto 1600°C. The microreactor was designed using 3D...

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...
