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,...

Prediction of mass transfer performance of microchannel dialyzersusing deconvolution of impulse-response experiments

Creator:: Anderson, Eric K.
Abstract:: The parallel implementation of a large number of functional units is necessary for any industrial scale microfluidic process. The concept of a 'numbering up' strategy where a single highly optimized functional unit that has a low individual production is replicated a large number of times to create a device that...

Numerical simulation of micro/mini-channel based methane-steam reformer

Creator:: Peterson, Daniel Alan
Abstract:: Numerical modeling of methane-steam reforming is performed in a micro/mini-channel with heat input through catalytic channel walls. The low-Mach number, variable density Navier-Stokes equations together with multicomponent reactions are solved using a parallel numerical framework. Methane-steam reforming is modeled by three reduced-order reactions occurring on the reactor walls. The surface...

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...

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,...

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...

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 Characterization of a Supercritical Carbon Dioxide Microchannel Solar Thermal Receiver

Creator:: L'Estrange, Thomas
Abstract:: Characterization of a microchannel solar thermal receiver for supercritical carbon dioxide (sCO₂) is presented. The receiver design is based on conjugate computational fluid dynamics and heat transfer simulations as well as thermo-mechanical stress analysis. Two lab scale receivers with a 2x2 cm² absorber area are fabricated and experimentally characterized -...

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...

Microchannel steam-methane reforming under constant and variable surface temperature distributions

Creator:: Eilers, Benn J.
Abstract:: Steam-methane reforming is a well understood industrial process used for generating hydrogen and synthesis gas. The reaction is generally carried out with residence times on the order of one second. By performing this reaction at microscales it is possible to take advantage of increased heat transfer rates and low diffusion...
