A microchannel-based thermal management system for hydrogen storage adsorbent beds

Creator:: Steigleder, Leif J.
Abstract:: Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...

Micromixer assisted continuous flow synthesis of nanoparticles of binary compounds and their application

Creator:: Palanisamy, Barath
Abstract:: In this work, continuous synthesis routes for binary nanoparticles using advantages of microchannel mixing (low diffusion distances and higher mass transfer) and fast heating rates provided by ultrasound induced heating are investigated. In addition, the application of silica nanoparticles in anti-reflective coatings on glass and understanding the structure property-performance correlation...

Fluidic and thermal modeling for the high production rate synthesis of high quality nanoparticles

Creator:: Peterson, Daniel Alan
Abstract:: Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...

Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

Creator:: Tseng, Chih-Heng
Abstract:: Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

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...

Fabrication of precipitation-hardened aluminum microchannel cooling plates for adsorption-based hydrogen storage systems

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...

Experimental investigation of supercritical heat transfer of carbon dioxide in parallel square microchannels with a single-wall constant heat flux boundary condition

Creator:: Zada, Kyle R.
Abstract:: In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...

Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

Creator:: Brannon, Samuel T.
Abstract:: High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

Intermetallic microlamination for high-temperature microreactors

Creator:: Dewey, Tyler
Abstract:: Chemical microreactors offer opportunities for portable power generation, on-site waste remediation and point-of-use chemical synthesis. Much of the existing development of microreactor devices involves silicon-based microfabrication techniques. It is recognized that new refractory materials are important to realizing high-temperature microreactors. Requirements of these materials include high-temperature resistance, chemical inertness and...

Synthesis, characterization and deposition of dendrimers using a continuous flow microreactor

Creator:: Liu, Shuhong
Abstract:: Dendrimers are nanoscale macromolecules that have highly branched, core-shell structures. Higher generation dendrimers have close-packed peripheral functional groups and a hollow interior. The chemistry of the core and the terminal functionalities can be tailored according to the specific application. These structural characteristics provide room for the design of dendrimers to...
