Spring 2016
Health care systems focus on fulfilling patient expectation and needs. However, the wide differences among various health care services make the understanding and use of patient satisfaction information challenging. Patient satisfaction can systematically be studied and analyzed through methods...

An open-source two-phase non-isothermal mathematical model of a polymer electrolyte membrane fuel cell
DownloadSpring 2014
A comprehensive open-source two-phase non-isothermal MEA model including the microporous layer and accounting for multi-step reaction kinetics for the ORR and HOR is developed for the first time. The model is integrated into openFCST, an open-source FEM based fuel cell simulation framework. All...

An Oxygen Reduction Reaction Kinetic Model for Proton Exchange Membrane Fuel Cells Based on Free Energies of Activation and Adsorption
DownloadSpring 2023
Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative technology to internal combustion engines used on vehicles. However, improvements on durability and performance are needed in order to boost the commercialization of this technology. The oxygen reduction reaction (ORR)...

Fall 2018
The work within this thesis is concerned with an unsteady flow phenomenon known as vortex shedding. It is ubiquitous throughout engineering applications and leads to unwanted noise, vibration, and pressure drop in the afflicted systems. Vortex shedding is highly complex, and even with over a...

Analysis of an Open-Cathode Fuel Cell Stack in an Enclosure for Varying Operating Conditions
DownloadSpring 2013
Open-cathode polymer electrolyte fuel cell (PEFC) stacks use hydrogen as a fuel, are a high efficiency power source, and do not produce CO2, NOx, SOx, or particulate matter. When used as a remote power source, the PEFC stack must be protected from adverse environmental conditions. To provide...

Analysis of Displacement in an Elastic Solid with a Mode-III Crack in the Presence of Surface Elasticity
DownloadFall 2011
The focus of this work is the study of anti-plane deformations of an elastic solid containing a crack. A more comprehensive model of the mechanism of fracture was found by incorporating surface mechanics on the crack face. Included are comparisons between the refined model and the classical model...
