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...

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...

Improved Quantification of Viscoelastic Effects during Polymer Flooding Using Extensional Rheology
DownloadSpring 2019
Polymer flooding is one of the traditional chemical enhanced oil recovery (EOR) methods with a high rate of success. Synthetic polymer such as hydrolyzed polyacrylamide (HPAM) characterized by flexible chain exhibits viscoelastic characteristics in porous media. Some of the implications of the...

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...

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...

Optimization of Drilling Fluid Rheological Properties for Improved Cuttings Transport and Dynamic Filtration Loss Control Performance: A Comparative Study of the Fluid Viscoelasticity versus the Shear Viscosity Effects
DownloadFall 2022
Recent studies highlighted the significant role of drilling fluid viscoelasticity in the assessment of frictional pressure loss, particle settling velocity, hole cleaning efficiency, and dynamic filtration loss control. Although the impact of drilling fluid viscoelasticity on the various...

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...

In modern cosmology, many efforts have been put to detect primordial B-mode of cosmic microwave background polarization from the gravitational waves generated during inflation. Considering the foreground dust contamination of microwave polarization maps, it is essential to obtain a precise...
