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...

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,...

Coke drums are vertical pressure vessels used in the delayed coking process in petroleum refineries. Significant temperature variation during the delayed coking process causes the useful life of coke drums to be shortened. In order to better understand the failure mechanisms, a experimental study...

Experimental study of methane decarbonization to produce hydrogen using a laminar premixed flame
DownloadSpring 2018
Hydrogen is a promising source of energy with various applications. The most common method of producing hydrogen is steam reforming of methane; however, thermal cracking of methane can be used alternatively for hydrogen production with less CO2 emissions. In this study, thermal cracking of...

EXPERIMENTAL STUDY OF THE GEOMETRIC CHARACTERISTICS OF BUBBLES/DROPLETS PASSING THROUGH A PORE SPACE
DownloadFall 2021
The multi-phase flow motion of droplets and bubbles through porous media has been reported for different applications. The importance of the effect of the presence of emulsions on the performance of steam-assisted gravity drainage (SAGD) for oil extraction is discussed as a relevant process. SAGD...
