Spring 2013
20Cr-32Ni-1Nb stainless steel alloys are commonly used in hydrogen reformer manifolds for transporting hot hydrogen by-products at 750-950 celcius. After long periods of exposure, embrittling secondary carbides and intermetallic phases can precipitate at the grain boundaries which can drastically...

Tools and Methodologies for The Rapid Determination and Transfer of Thermodynamic Parameters used in the Prediction of Gas Chromatographic and Two Dimensional Comprehensive Gas Chromatographic Retention Times
DownloadFall 2014
Three parameter thermodynamic predictive models have been shown previously to provide superior accuracy in the prediction of gas chromatographic retention times in comparison to other forms of modelling such as retention indices. However, these models suffer from the need for extensive...

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...

Developing High Precision Heat Capacity Correlations for Organic Solids and Liquids - Extending to Biofuels and Sugars
DownloadSpring 2018
There is a great need for easily accessible and accurate physical property data in the heavy oil industry, the pharmaceutical industry, and other heavy molecule guided productions. In recent years, high precision predictive correlations for isobaric heat capacities of heavy and ill-defined...

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...

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...

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...

Validation and Testing of a Numerical Model for the Design and Up-Scaling of Low Temperature Difference Stirling Engines
DownloadSpring 2023
This thesis presents the experimental validation, testing and review of a numerical model for low temperature difference Stirling engines (LTDSEs). The research of LTDSEs is motivated by the potential use of low temperature heat as an unconventional sustainable energy source. An experimental...
