Development Towards a Three-Component Three-Dimensional Micro Velocity Measurement Technique
DownloadFall 2012
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 Pipelines
DownloadFall 2012
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 and Theoretical Investigations of Particle Removal from Sand Bed Deposits in Horizontal Wells Using Turbulent Flow of Water and Polymer Fluids
DownloadFall 2017
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...

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 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...

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 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...

Newtonian and Non-Newtonian Flows through Mini-channels and Micro-scale Orifices for SAGD Applications
DownloadSpring 2016
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...
