Fall 2014
In today’s vehicle applications, Selective Catalytic Reduction (SCR) ammonia dosing is completed using complex control algorithms that need to be parameterized for the individual catalytic converter technology. The parameterization of these control strategies is not always completed during the...

Global kinetic model for a Pt-Pd diesel oxidation catalyst (DOC) is proposed and validated. Experimental data was obtained using different concentrations of the artificial gas mixtures which were passed over a bimetallic catalyst. Previous works of Voltz [1], Pandya [2], Sola [3] and many others...

Hosseininejad, Seyed Shaham Aldin
To overcome the challenges of low recovery of fine particles in flotation processes, designing a cavitating device that can enhance the recovery has been a major topic of study. In the design of a cavitating device, the bubble/bubble interactions, bubble response to the change of local pressure,...

Characterization of natural zeolite membranes for H2/CO2 separations by single gas permeation
DownloadFall 2011
Hoseinzadeh Hejazi, Sayed Alireza
Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

Fall 2017
High Chromium Cast Irons (HCCIs) are widely used in mineral processing, slurry pumping and manufacturing processes, where high resistance to erosion and synergetic erosion-corrosion is required. The excellent performance of HCCIs results from their microstructure, which consists of hard carbides...

Computer simulation and experimental characterization of a tubular micro- solid oxide fuel cell
DownloadSpring 2010
This work is focused on a state-of-the-art tubular micro-solid oxide fuel cell (TμSOFC), ~3 millimeters in diameter and ~300 microns thick, with Ni/YSZ and LSM/YSZ composite electrodes and a YSZ electrolyte. A 2D axi-symmetric, multi-scale CFD model is developed which includes the fluid flow,...

Fall 2009
The present work deals with the development of a direct simulation strategy for solving the motion of spherical particles in non-Newtonian liquids. The purely viscous (non-elastic) non-Newtonian liquids are described by Bingham and thixotropy models. Validation of the strategy is performed for...

Finite Element Model of the Thermal Profile During Submerged Arc Welding with One and Two Electrodes
DownloadFall 2016
The submerged-arc welding (SAW) process is used extensively in the manufacturing of pipes. The heat flow introduced by the welding operation has a significant impact on the properties of both the weld metal and the heat affected zone (HAZ). The work presented in this thesis aims to develop a...

Using data from artificial gas mixtures, global kinetic models for a platinum diesel oxidation catalyst are developed. The modelling of CO and C3H6 was inspired by the classical work of Voltz et al.[1], while the modelling of NO and C3H6 was based on the earlier work of Pandya[2], Mulla et...
