Particle image velocimetry/ tracking in turbulent flow over riblet surfaces with superhydrophobic coating
DownloadFall 2016
Riblet surfaces have been introduced as of one successful technique to reduce skin-friction. Advanced particle image velocimetry (PIV) and particle tracking velocimetry (PTV) are employed to investigate turbulent structures over riblet surfaces by several researchers including Suzuki and Kasagi...

Transition From Laminar to Turbulent Flow in Non-Newtonian Channel Flows: The Impact of Drag Reducing Polymer Additives
DownloadFall 2023
This thesis investigates the effect of a drag-reducing polymer on laminar-turbulent transition in a gravity-driven channel flow. The drag-reducing polymer is polyacrylamide (PAM) dissolved in water at concentrations of 50, 75, 100, and 150 parts per million (ppm). An extensive experimental...
