Fall 2021
Middleton, Steven Mark William
A numerical model and software interface for the design and modelling of Stirling engines was presented. This model was developed to suit low-temperature Stirling engines, those that run at source temperature of less than 150 °C and run at speeds where temporarily developed losses become...

Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...

Application of Ozone and Peroxone Processes for Naphthenic Acids Degradation in Oil Sands Process-Affected Water: Characterization of Water Before and After Treatment
DownloadFall 2017
Appling ozone (O3) with high doses (>100 mg/L) to remove naphthenic acids (NAs) from oil sands process-affected water (OSPW); limits its application and feasibility in the OSPW remediation. To decrease the required doses and their associated costs, this study examined the application of ozone...

Effect of Heat Exchanger Volume and Geometry on Power Output of a Low Temperature Difference Stirling Engine
DownloadFall 2022
This work presents the results of an investigation into heat exchanger design for low temperature difference Stirling engines (LTDSEs). The aim of this study was to determine if there is an optimum heat exchanger geometry for producing maximum power output for a LTDSE. There are multiple factors...

Forward Osmosis as an Approach to Manage Oil Sands Produced Water: Membrane Fouling and Organic Removal
DownloadFall 2017
Currently, large amounts of oil sands process-affected water (OSPW) are stored in tailing ponds, leaving its environmental impact a significant concern. To better manage OSPW, numerous treatment approaches have been investigated including adsorption, advanced oxidation and biological treatment,...

Thermodynamic Investigation of the Effect of Interface Curvature on Solid-Liquid Equilibrium and Its Application to Zinc-Air Battery Electrolyte at Low Temperature
DownloadSpring 2018
Micro and nanoscale confinements and local curvatures, which are ubiquitous in natural and man-made materials and systems, cause significant impact on thermodynamic phase behavior. This effect has been extensively studied for single component solid's liquid phase transitions, but rarely for...
