Fall 2010
A robotically-controlled actuation system has been developed and built to perform active open-loop flow control experiments on transitional and turbulent backward-facing step flows in water. Control of the reattaching shear layer used hydraulic suction-and-blowing actuation emanating from 128...

Design and Use of Servo-Driven Actuators for Spanwise-Varying Control of a Backward-Facing Step Flow
DownloadSpring 2012
An experimental study was conducted of a forced backward-facing step water flow, and the design of 16 actuators for creating the perturbations used to force the flow. The 16 actuators allowed for variant forcing in the spanwise direction with a resolution of 0.5 times the step height h. They are...

Experiments and Computer Simulations on Aerodynamic Drag Reduction of Light Vehicle-Trailer Systems
DownloadFall 2015
Wind-tunnel experiments and Computational Fluid Dynamics (CFD) were performed to study the effect a deflector had on the flow and drag force associated with a 2010 F-150 truck and cargo trailer (Light Vehicle-Trailer System - LVTS). Image Correlation Velocimetry (ICV) on smokewire streaklines...

Fall 2010
Computational simulations of a perturbed vortex ring are performed to recreate and understand the instability seen in impacting water droplet experiments. Three initial conditions are tried to respectively trigger a Widnall instability, a Rayleigh centrifugal instability, and a vortex breakdown...
