Force Prediction in the Compression Sealing of an Ultra-thin Elastoviscoplastic Membrane

Creator:: McNeff, Patrick Scot
Abstract:: The objective of this paper is to demonstrate a method for mechanically characterizing a 25 μm thick elastoviscoplastic hemodialysis membrane and for quantifying the force required to use that membrane in compression sealing. First, methods are developed for mechanically characterizing the thin elastoviscoplastic membrane. Then, a finite element model is...

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...

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...

Process Physics, Strategies and Economics in Metal Additive Manufacturing and Digital Microstructural Control for Energy and Chemical Process Components

Creator:: Manoharan, Sriram
Abstract:: Advances in plant construction within the energy and chemical process industries require inexpensive process intensification (PI) technology as a means to reduce plant size for enabling modular construction. One form of PI is microchannel process technology where arrays of microchannels, having hydraulic diameters on the order of 0.1 to 1...

Uniform residence time in microreactor-assisted solution deposition of CdS thin-films for CIGS photovoltaic cells

Creator:: Hires, Clayton Lamar
Abstract:: Photovoltaic (PV) cells have long been an attractive alternative for the consumption of fossil fuels but current manufacturing practices suffer from poor energy efficiency, large carbon footprints, low material utilization, high processing temperatures and high solvent usage. A critical step in PV production is the deposition of CdS as a...

Nanoparticle-assisted diffusion brazing of metal microchannel arrays : nanoparticle synthesis, deposition, and characterization

Creator:: Eluri, Ravindranadh T.
Abstract:: Microchannel process technology (MPT) offers several advantages to the field of nanomanufacturing: 1) improved process control over very short time intervals owing to shorter diffusional distances; and 2) reduced reactor size due to high surface area to volume ratios and enhanced heat and mass transfer. The objective of this thesis...

Manufacturing Process Design and Electrically-Assisted Embossing of a Microchannel Solar Receiver

Creator:: McNeff, Patrick S.
Abstract:: Manufacturing process design (MPD) represents a design-oriented approach to manufacturing engineering. In this dissertation, Haynes 230 (H230), a solid solution-strengthened Ni-based superalloy, was chosen to meet the material requirements of a microchannel solar receiver (MSR) needed to increase the efficiency and reduce the cost of solar thermal power generation. An...

Application of controlled thermal expansion in diffusion bonding for the high-volume microlamination of MECS devices

Creator:: Pluess, Christoph
Abstract:: Diffusion bonding has been widely used within microlamination architectures for the fabrication of Micro Energy and Chemical Systems (MECS). MECS are microsystems with the ability to process bulk amounts of fluid within highly-parallel microchannel arrays capable of accelerated heat and mass transfer. Thus far, diffusion bonding of the microchannel arrays...

A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

Creator:: Kawula, Steven P.
Abstract:: Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...
