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...

The enormous volumes of oil sands process-affected water (OSPW) produced during oil sands bitumen extraction have been a public concern due to the toxicity and persistence of the organic contaminants contained in the water. Among all the contaminants in OSPW, naphthenic acids (NAs) are regarded...

Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Fischer—Tropsch gas loops have been in use for nearly a century, producing synthetic fuels and petrochemicals. Yet there still remain many opportunities to expand its uses, update the gas loop with new technology, as well as better understand at a fundamental level the way the products behave....

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...

This dissertation investigates the influence of surface heterogeneities on colloid deposition. First, deposition of colloidal particles on a nanofiltration membrane during cross flow membrane filtration was studied under different operating pressures and solution chemistries. An atomic force...

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...

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...

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...
