It is well known that long-chain polymers and surfactants can significantly reduce the skin-friction drag of turbulent liquid flows; a phenomenon often referred to as rheological drag reduction. However, it is unclear if the mechanism for drag reduction is common among different types of polymers...

The fluid mechanics literature suggests that the ability to manipulate the very-large-scale motions (VLSMs) that exist within turbulent boundary layers (TBLs) would provide influence over the unwanted drag forces, noise, and vibrations associated with these flows. The ability to suppress these...

The work within this thesis is concerned with an unsteady flow phenomenon known as vortex shedding. It is ubiquitous throughout engineering applications and leads to unwanted noise, vibration, and pressure drop in the afflicted systems. Vortex shedding is highly complex, and even with over a...

The near wake behind the Ahmed body at zero-yaw has been extensively studied in the past, but comparatively little is known about the changes in the wake flow patterns during crossflow. Measurements of the near wake of a square-back Ahmed body were obtained at a Reynolds Number of ReH = 9.2104...

Thickened tailings technology is implemented in some oil sands operations in order to recycle warm process water, thereby reducing net water draw, and to reduce the size of tailings impoundment areas. The rheology of thickened tailings is complex and time-dependent, and the underlying mechanism...

In oil sands extraction, the removal of heavy materials from a bitumen feed is often facilitated by solvent addition treatment processes. These processes mix solvent with bitumen feed to cause the precipitation of heavy products. The settling properties of these heavy products as they separate...

To enhance the aerodynamic performance of a vehicle, a fundamental understanding of the flow is required. This can be achieved through flow characterization of simplified models such as the Ahmed body. However, uncertainties regarding the topology of flow motions in the wake persist due to the...

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...

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...

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...
