Completed Projects

This project investigates the use of active flow control on square bluff bodies relevant to tall buildings. The research seeks to ameliorate the unsteady loading by controlling the formation and development of the von-Kármán vortex street, which is known to be the cause of undesirable building motion. More specifically, a fluidic jet is periodically excited at each of leading edges of a square prism where the shear layers separate and evolve into the large-scale vortex shedding in the wake.

Recent developments in flow control techniques, coupled with increased interest in green energy technologies, have led to interest in applying flow control techniques to wind turbines, in an effort to reduce structural stress associated with widely varying loading.

Developing a single propulsion and control concept for UUV’s that can provide more degrees of freedom and better control effectiveness compared with current technologies.

Applying bio-mimicry intelligence to the aerodynamic performance of tall slender buildings has potential to lead to not only improved response to wind loading, but generate savings in material and construction costs, affect energy consumption by providing self-shading and controlling local air flow to promote local wind energy generation and ventilation strategies.

experimental investigation was performed to study the formation of secondary flow structures due to the interaction of a finite-span synthetic jet with a three-dimensional boundary layer over a finite and swept-back wing configuration (cross-sectional profile of the NACA 4421, aspect ratio of 4 and sweep back angle of 30o).

This research project is to explore the evolution of a synthetic (zero net mass flux) jet and the flow mechanisms of its interaction with a cross flow.
