Experimental investigation of drag reduction by polymer additives in a turbulent channel flow
DownloadSpring 2018
The addition of a minute amount of long-chain polymer molecules to a turbulent flow can cause a significant reduction of skin-friction drag in both internal and external flows. The explanation of interaction between polymers and turbulence remains the most difficult area of polymer flow...

Experimental Investigation of Heat Transfer and Pressure Drop of Pipes with Internal Roughness
DownloadFall 2022
In many industrial heat exchangers, it is desirable to improve the rate of heat transfer from a pipe wall to the fluid flow. This improvement is commonly made by adding some form of roughness to the pipe surface. However, the added roughness often leads to an increase in the pressure drop of the...

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...

Spring 2024
The purpose of this thesis is to obtain a better understanding of the behavior of particles within a particle-laden turbulent channel flow, as well as evaluate the suitability of the flow facility to measure particle-laden flows. Suitability of the flow loop for measurements of particle-laden...

Fall 2020
The transportation of mixtures of particles and liquids using slurry pipelines plays a crucial role in the petroleum and mining industries. Slurry pipeline flows are typically turbulent and the presence of the particulate phase results in pipe wear and increased pumping cost. As a result, slurry...

Fall 2011
An experimental technique to quantify velocity field at pore scale within micro porous media, formed by packing of micro glass spheres inside a glass micro-model, is presented. A scanning micro particle image velocimetry (µ-PIV) system is used to obtain two component two dimensional (2C2D)...

Experimental Investigation of Stirling Engine Modelling Techniques at Reduced Source Temperatures
DownloadFall 2019
A Stirling engine was studied experimentally with two objectives. The first was to determine the effects of flywheel polar moment of inertia on the transient and steady-state performance of a Stirling engine. The second was to investigate the accuracy of a 2nd order thermodynamic model with a...

Fall 2024
Much research has been performed over the past few decades on heat pipe performance enhancement. A major thrust of investigation has been to examine factors impacting condensation. Measurements suggest that drop-wise condensation achieves a comparatively larger rate of condensate discharge on...
