Spring 2018
Natural Resources Canada (NRCan) has been using an autonomous underwater vehicle (AUV) to map the vast Canadian Artic seabed. The logistics of under-ice survey is currently complicated due to limited lifetime of lithium-ion batteries of AUVs. An AUV with longer endurance would allow exploration...

EXPERIMENTAL INVESTIGATION OF THE SETTLING VELOCITY OF SPHERICAL PARTICLES IN VISCOELASTIC FLUIDS
DownloadFall 2017
Knowledge of settling behavior of particles in various types of fluids is indispensable to design and optimize numerous industrial operations such as cuttings transport in oil and gas well drilling, proppant transport in hydraulic fracturing operations, and so on. Most of the models developed so...

Experimental Investigation of Near-well Fluid Mechanics on the Scaling Mechanism in Narrow Rectangular Slots
DownloadSpring 2020
This experimental study investigates the effect of near-well fluid mechanics on the scaling failure mechanism specific to SAGD production well. The scaling failure mechanism can be triggered by the pressure drop phenomenon and causes the plugging of the slots in the oilfields. The scale formation...

Investigating the Performance of Randomly Patterned Superhydrophobic Surfaces in Laminar and Turbulent Channel Flows
DownloadSpring 2019
Superhydrophobic surfaces (SHSs) have been investigated based on their success in water repellency, anti-fouling, and drag reducing effects seen in nature (Neinhuis & Bartlott 1997; Kreuz et al. 2001). SHSs utilize a low surface energy material with a microscale surface roughness to prevent water...

Fall 2010
This study experimentally evaluated wheat straw slurry pipelines. Tests were conducted to determine the particle properties of the biomass mixed in water over time. The saturated particle density of 1,060kg/m3 was reached after 24 hours, while the saturated moisture contents of 78.5% and 79.5%...

Transition From Laminar to Turbulent Flow in Non-Newtonian Channel Flows: The Impact of Drag Reducing Polymer Additives
DownloadFall 2023
This thesis investigates the effect of a drag-reducing polymer on laminar-turbulent transition in a gravity-driven channel flow. The drag-reducing polymer is polyacrylamide (PAM) dissolved in water at concentrations of 50, 75, 100, and 150 parts per million (ppm). An extensive experimental...

Wind Tunnel Investigation of the Effect of Duct and Cross-flow on Small Propellers for Unmanned Aerial Vehicles
DownloadFall 2018
The expanding field of unmanned aerial vehicles (UAV) has introduced a variety of flight operating conditions and thus, performance requirements. As a method to improve performance in the propulsion systems of UAVs, two topics of interest are emphasized in this thesis: the potential improvements...
