Fall 2012
Underground Coal Gasification (UCG) is a process in which coal is converted to syngas in-situ. UCG has gained popularity recently as it could be used to extract energy of deep-lying coal seams, and it reduces the footprints attributed to the gasification process. In this study, two models have...

Complex concentrated slurry flows in horizontal pipelines are widely seen in many industries for transportation of solid particles or process wastes. i.e., tailings. Slurry flows can occur in a turbulent regime, and the carrier fluid usually shows a non–Newtonian behavior. Understanding the flow...

Fall 2015
This work is devoted to the CFD analysis of multiphase flow using Euler-Euler model. In particular, Euler-Euler multiphase model is applied to study numerically the behaviour of gas-solid system and solid-liquid system. The main objective of this work is to validate Euler-Euler multiphase model...

Challenges in computational modeling of two-phase transport in polymer electrolyte fuel cells flow channels: a review
Download2017-01-01
Excess of liquid water in gas channels of polymer electrolyte fuel cells is responsible for malfunctioning of these devices. Not only it decreases their efficiency via partial blockage of reactants and pressure drop, but it can also lead to the irreversible damage due to oxygen starvation in case...

Characterization of Athabasca asphaltenes separated physically and chemically using small-angle X-ray scattering
DownloadFall 2010
Athabasca asphaltenes were characterized using small-angle X-ray scattering (SAXS) with synchrotron radiation. Two methods were used to separate asphaltenes from Athabasca bitumen. Conventional chemical separation by precipitation with n-pentane, and physical separation realized by passing...

Characterization of asphaltene molecular structures by cracking under hydrogenation conditions and prediction of the viscosity reduction from visbreaking of heavy oils
DownloadSpring 2013
The chemical building blocks that comprise petroleum asphaltenes were determined by cracking samples under conditions that minimized alterations to aromatic and cycloalkyl groups. Hydrogenation conditions that used tetralin as hydrogen-donor solvent, with an iron-based catalyst, allowed...

Fall 2009
In this study, we describe the use of different silica materials to separate vanadium compounds from Asphaltenes. We used high performance flash chromatography separation method to separate asphaltenes at different solvent strengths on sea sand. The separation conditions were optimized for flow...

Computational Fluid Dynamics Validation of Rooftop Wind Regime in Complex Urban Environment
DownloadSpring 2020
This thesis presents a validation methodology for Computational Fluid Dynamics (CFD) assessments of rooftop wind regime in urban environments. A case study is carried out at the Donadeo Innovation Centre for Engineering (DICE) building at the University of Alberta campus. A numerical assessment...

To understand the water cycle on Mars, details of mass and energy transfer between the surface and the atmosphere are of importance. A complete model, involving transient variations of the water in gaseous and solid phases in the atmosphere and the regolith, is developed and solved numerically...

Spring 2015
This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...
