Dr. Redha Wahidi specializes in experimental fluid dynamics with basic and applied research interests in unsteady flows, high-speed aerodynamics and flow control. His current research projects focus on unsteady vortex-body interaction (U-VBI) and three-dimensional shock-wave/boundary-layer interactions (3D-SBLI).
In the U-VBI research, Dr. Wahidi explores the flow physics of the interaction of large-scale vortices with oscillating wings to help improve the performance of helicopter rotors and turbine blades. He conducts the experiments in water tunnel and subsonic wind tunnel facilities and uses three-dimensional particle image velocimetry (3D-PIV) to obtain high-fidelity measurements of the flow field.
The SBLI research aims to investigate the flow physics of shock-wave interactions with the boundary layers forming on stationary and moving three-dimensional bodies. Dr. Wahidi conducts the experiments in a supersonic wind tunnel. He employs several qualitative (shadowgraph, surface-oil flow visualization) and quantitative (3D-PIV, 2D PIV, and steady and unsteady pressure measurements) experimental techniques to gain a better understanding.
