Casing pipes used in sour service are prone to two forms of failure: hydrogen induced cracking (HIC) and sulfide stress cracking (SSC). The objective of this thesis is to investigate the resistance of L80 ERW and Seamless steel pipe, with five different chemical compositions, to both HIC and SSC....

Investigation of the Adsorption of Model and Oil Sands Process-Affected Water Naphthenic Acids on Graphite
DownloadSpring 2015
Naphthenic acids (NAs) are constituents of bitumen in the oil sands deposits in northern Alberta, Canada. The extraction process of bitumen creates an enormous amount of wastewater called oil sands process affected waters (OSPW). This OSPW contains elevated concentrations of NAs, and other...

Machine Learning for Emission Modeling of Fossil-fueled and Hydrogen-fueled Internal Combustion Engines
DownloadFall 2023
Development of fast and accurate emission models for engine-out and tailpipe of internal combustion engines (ICEs) using machine learning (ML) and hybrid methods are the focus of this thesis. The application is on medium and heavy-duty vehicles powered by both fossil fuels and alternative fuels...

Probing Surface Heterogeneity, Electrochemical Properties and Bubble-Solid Interaction Mechanisms of Sulfide Minerals in Flotation
DownloadSpring 2017
The colloidal stability governed by various surface interactions including van der Waals (VDW) interaction, electrical double layer (EDL) interaction, hydrophobic interaction, and some other interactions, plays an important role in a wide range of natural phenomena and engineering applications....

Confinement is known to suppress order in condensed matter. This is well exemplified in phase transitions such as freezing, as well as the superfluid transition in liquid helium, which occur at lower temperatures in confinement than in the bulk. We provide in this thesis a demonstration of a...

Surface Interaction Mechanisms between Deformable Bubbles and Hydrophobic Surfaces in Aqueous Solutions
DownloadSpring 2018
Deformable bubbles in complex fluidic systems are crucial components in a variety of traditional and emerging industrial processes, where their surface interactions with hydrophobic surfaces play an important role in realizing the targeted functionalities. In this project, a bubble probe atomic...
