Abstract

Vortex shedding occurs from commonly encountered objects in ows such as blunt and divergent (truncated) airfoil trailing edges [12], landing gear of aircraft [37], etc. In addition to undesired aero-elastic effects such as vortex-induced vibration and uctuating aerodynamic forces, tonal acoustic noise is emitted due to the regular and periodic nature of the shedding. With the aim of eliminating this emitted noise, an experimental study was carried out on a D-shaped bluff body model using appropriately designed and implemented plasma actuator configurations to achieve active three-dimensional vortex shedding suppression.
