Finite Element Model of the Thermal Profile During Submerged Arc Welding with One and Two Electrodes
DownloadFall 2016
The submerged-arc welding (SAW) process is used extensively in the manufacturing of pipes. The heat flow introduced by the welding operation has a significant impact on the properties of both the weld metal and the heat affected zone (HAZ). The work presented in this thesis aims to develop a...

Developing and testing methods to assess species extinction risk and ecosystem degeneration
DownloadFall 2016
Species worldwide are becoming increasingly threatened due to the rapid changes in climate and land use induced by human activities. The loss of species threatens the provision of food, goods and many other ecosystem services essential to the sustainability and well-being of human society. It is...

Methane (CH4) is a greenhouse gas with an elevated global warming potential (GWP) equivalent to 28 times that of CO2. Also, production of enteric CH4 results in a 2 to 12% loss of the gross energy intake of cattle thus knowing the amount of CH4 released to the environment is important. The...

Hosseininejad, Seyed Shaham Aldin
To overcome the challenges of low recovery of fine particles in flotation processes, designing a cavitating device that can enhance the recovery has been a major topic of study. In the design of a cavitating device, the bubble/bubble interactions, bubble response to the change of local pressure,...

Numerical Simulation Of Water Flow Through Unsaturated Soil In Vertical And Inclined Layered Systems
DownloadSpring 2016
In past decades, there were discussions explaining the mechanisms and factors that influence water flow through soil in unsaturated conditions. This phenomenon is of major importance to the mining industry as water is one of the trigger mechanisms for Acid Rock Generation (ARD) generation. In...

Two-Dimensional Modeling of the Effect of Relative Humidity on Volatile Organic Compounds Adsorption in a Fixed Bed Adsorber
DownloadFall 2017
Water vapor can affect adsorption of volatile organic compound (VOC) onto activated carbon. In this research, a two-dimensional heterogenous computational fluid dynamics model was developed and validated to understand the mechanism and kinetics during competitive adsorption between VOC and water...

Fall 2017
This work focuses on validation of a commercial computational fluid dynamics (CFD) software ANSYS Fluent 16.2 applied to multi-phase modeling of fluidized beds. A two-phase Eulerian-Eulerian based model is used to numerically reproduce experiments carried out by Taghipour, F. et al (Chem. Eng....

Development, Modelling and Control of a Continuous Pilot Scale Supercritical Fluid Extraction Process
DownloadSpring 2017
In this thesis, the feasibility and operation of a continuous pilot scale supercritical fluid extraction (SFE) process for treatment of oil-contaminated solids, specifically drill cuttings, was investigated. For this purpose, a continuous pilot scale SFE process, the first of its kind, was...
