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...

Numerical Characterization of Ultrasound Elastography for the Early Detection of Deep Tissue Injuries
DownloadFall 2014
Deep tissue injuries - casually termed "bedsores" or "pressure ulcers" - are a type of wound often suffered as secondary injuries in persons with reduced mobility such as those with spinal cord injuries, the elderly, and people with multiple sclerosis. Deep tissue injuries form when excess...

Heterogeneity of surfaces is often included in mathematical treatments of colloid transport and deposition as an afterthought, if at all. Most previous models of colloid transport and deposition have employed idealizations and simplifications such as assuming smooth collector surfaces with...

Computational simulations of a perturbed vortex ring are performed to recreate and understand the instability seen in impacting water droplet experiments. Three initial conditions are tried to respectively trigger a Widnall instability, a Rayleigh centrifugal instability, and a vortex breakdown...

Modelling of PEMFC Catalyst Layer Mass Transport and Electro-Chemical Reactions Using Multi-scale Simulations
DownloadFall 2014
The focus of this work is on improving understanding of mass transport limiting phenomena occurring within the micro-structure of Polymer Electrolyte Fuel Cell (PEFC) Catalyst Layers (CL). Micro-scale models, namely agglomerates, are employed within multi-scale CL framework, to examine many...

This thesis focuses on the use of computer simulation for modeling risk of a multi-state repairable component. In production processes, maintenance decisions are often made based on uncertain assessment of risk, not only in the probability when a process component goes into a state of failure...

Mathematical modeling and experimental validation of thin low platinum content and functionally graded cathode catalyst layers
DownloadFall 2014
Low catalyst content remains a key requirement for the commercialization of polymer electrolyte fuel cells (PEFCs) into the energy, transportation, and material handling sectors. Understanding the fundamental phenomena reducing fuel cell performance at various stages of operation play a major...

Steam assisted gravity drainage (SAGD) is one of the most popular methods used for heavy oil extraction in Canada. Of the existing sand control methods that can be used for SAGD, slotted liners can be considered among the superior ones in terms of their performance and cost of manufacturing. RGL...
