Experimental Investigation of the Effect of NaCl Additive on the Formation and Evolution of Particles in a Diffusion Flame
DownloadSpring 2017
Formation and evolution of nano-particles in a laminar co-flow methane diffusion flame were investigated under two conditions: a pure methane flame and a methane flame doped with NaCl particles. Samples of nano-particles from different heights above the burner were extracted by a probe sampling...

Helicopters have proven to be a versatile air vehicle in today’s society and are used in a variety of applications. Many complexities arise in the aerodynamics of helicopters due to the presence of the main rotor downwash and the diverse range of flight conditions. The various uses of helicopters...

Spring 2020
A reduction in skin-friction drag can lead to lower energy consumption in variety of transportation vehicles, and consequently results in a smaller environmental impact. Several methods have been presented to reduce the skin-fiction and one of these methods is to introduce an air layer at the...

Experimental Investigation of Viscoelastic Cavitating and Turbulent Channel Flows Subjected to Different Pressure Gradients
DownloadSpring 2023
Steam-assisted gravity drainage is a common method for oil production in Alberta, Canada. Production wells are equipped with inflow control devices to improve production efficiency. These devices utilize nozzle-type constrictions to enhance oil production by hindering water and gas breakthroughs....

Experimental investigation on evaporation induced convection in water using laser based measurement techniques
DownloadFall 2010
Recent studies showed that evaporation of water can induce surface tension gradients along the water surface and ultimately lead to convection, known as Marangoni convection. This study was devoted to visualization and characterization of the evaporation-induced, surface-tension-driven convection...

Experimental Measurement of Mass Transport Parameters of Gas Diffusion Layer and Catalyst Layer in PEM Fuel Cell
DownloadFall 2019
A diffusion bridge is modified to accurately measure the in-plane permeability and diffusivity of gas diffusion layers (GDLs), and to measure the through-plane permeability, effective pore diameter, Knudsen diffusivity and effective diffusivity of catalyst layers (CLs). In order to measure...

Experimental Studies and Multi-Scale Modelling of Advanced Ceramics: Fracture, Fragmentation, and Failure
DownloadFall 2024
The objectives of this thesis is to explores the mechanical behaviour of alumina ceramics, focusing on fracture and fragmentation response through a blend of experimental investigations and advanced computational modelling. To bridge the gap between micro-mechanisms and macroscopic material...

Fall 2018
Creep is defined as the “progressive deformation of a material with time under constant load” and is of primary concern in structural design. This research sought to study the creep behaviour of braided composites. This information could be used to infer how fiber reinforced polymer (FRP) rebars,...
