Fall 2013
Habibzadeh Gharehbaba, Alireza
The current work presents the results of an experimental study on the effects of submergence on the performance of a submerged hydraulic jump with baffle blocks downstream of a sluice gate. A wide range of Froude numbers, submergence factors, and block sizes, locations and arrangements were...

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...

Performance evaluation, wake study, and flow visualization of air and large diameter water droplets around the blade of a micro horizontal axis wind turbine
DownloadSpring 2011
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...

Resistance and Membrane Fluidity of Endospores of Clostridium spp. During Pressure-Assisted Thermal Processing in the Presence of Antimicrobials
DownloadSpring 2012
Endospores of Clostridium spp. pose an economic threat to the food industry and put consumers at risk of foodborne illness. An increase in consumer demand for minimally-processed, ready-to-eat products has driven research to examine ways to mitigate current thermal processing severity used to...

Fall 2012
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...

Fall 2016
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...

Transport of Bubbles and Oil Droplets Rising in a Net Co-F1ow through a Rectangular Confinement
DownloadFall 2018
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...

Fall 2015
Superhydrophobic surfaces are proven to be capable of reducing the skin friction in laminar and turbulent flows. These surfaces consist of micro/nano-scale hydrophobic roughness features which make the surface render a non-wetting property due to the entrainment of air pockets between the solid...
