  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...
