An investigation towards determining the sources of uncertainty of a three-component three dimensional (3C3D) velocity measurement technique has been performed. The concept of the technique is velocity vector calculation based on 3D cross correlation of the intensity volume of positions of...
Effect of Near-Wall Turbulence on Selective Removal of Particles from Sand Beds Deposited in PipelinesDownload
A large-scale experimental facility was designed, constructed, and operated to study multiphase flow of solid-liquid mixtures (i.e., slurry flow) in horizontal pipelines. Trains of discrete lenticular deposits (LDs) and continuous beds were identified and studied in detail, representing two...
Experimental Investigation of Near-well Fluid Mechanics on the Scaling Mechanism in Narrow Rectangular SlotsDownload
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...
Experimental and Theoretical Investigations of Particle Removal from Sand Bed Deposits in Horizontal Wells Using Turbulent Flow of Water and Polymer FluidsDownload
Turbulent flow of water and polymer fluids over the sand bed deposits in horizontal annuli was studied using a large-scale flow loop equipped with particle image velocimetry (PIV) tool. Tests have been conducted to investigate the effects of near wall turbulence, fluid rheological characteristics...
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...
Newtonian and Non-Newtonian Flows through Mini-channels and Micro-scale Orifices for SAGD ApplicationsDownload
This experimental investigation examined the inflow to a producer well geometry found in a typical steam assisted gravity drainage (SAGD) process. The flow of Newtonian and non-Newtonian fluid through mini-channels (Dh = 0.837 µm) and micro-scale orifices (keystone slots, Dh = 0.858 µm) were...
Performance evaluation, wake study, and flow visualization of air and large diameter water droplets around the blade of a micro horizontal axis wind turbineDownload
This thesis presents a performance evaluation of a micro horizontal axis wind turbine, investigates the use of particle image velocimetry (PIV) to capture the flow field around a rotating blade and to track water droplets in the flow. The testing was done in a low speed wind tunnel in a highly...
The ability to control large vortices in the wake of an unsteady body is studied experimentally. A single airfoil in a uniform flow is forced to oscillate sinusoidally about its aerodynamic center and the resulting wake is expected to be dominated by large coherent vortices The wakes for several...
There are numerous examples of dispersed turbulent two-phase flows in engineering and environmental processes. In particular, dispersed solid-liquid flows, also known as slurry flows, have many industrial applications such as transportation of coal, ore, and oil sands. Slurry transportation...
The passage of air bubbles and oil droplets with five net co-flow through a vertical straight rectangular flow channel is investigated experimentally and theoretically in this research. A flow channel, varying from 22 mm × 5.84 mm to 3 mm × 5.84 mm (width × thickness) cross-sectional geometry was...
