Experiments investigating momentum transfer, turbulence and air-water gas transfer in a wind wave tank
DownloadSpring 2011
A series of laboratory experiments were conducted at three fetches of 4.8, 8.8 and 12.4 m, and at six wind speeds ranging from 4.1 to 9.6 m/s at each fetch in a wind-wave-current research facility. In addition, five surfactant-influenced experiments were conducted at concentrations ranging from...

Exploration of the effects of pressure and temperature on the evaporation rate of selected liquids
DownloadFall 2009
The rate of evaporation of liquids has been a topic of research for over a century. A detailed understanding of this phenomena is required to make scientific advancements in various areas. The principal objective for conducting this work was to study the effect of pressure on the rate of...

We report upon an experimental study of internal gravity waves generated by the large-amplitude vertical oscillations of a circular cylinder in uniformly stratified fluid. Quantitative measurements are performed using a modified synthetic schlieren technique for strongly stratified solutions of...

Internal gravity waves transport energy and momentum in both the atmosphere and the ocean. This physical process occurs at such small length scales that it is not captured by coarse resolution numerical models of weather and climate. A series of experiments is presented that model the generation...

The Monaco Glacier reaches sea level on the north coast of Spitzbergen, Norway. The fresh water flowing under the glacier mixes with sea water and creates the turbulence visible in the photograph. This brings sea life to the surface and attracts thousands of sea birds to the area. August 2008

Turbulence is a chaotic motion of fluid that can be described by the Navier--Stokes equations or even highly simplified shell models. Under the continuum limit, standard shell models of turbulence are shown to reduce to a common evolution equation that reproduces many predictions of the...

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...
