Pulse modulation of synthetic jet actuators for control of separation

Abstract
We investigate vortex shedding off an airfoil generated by pulsed actuation (or pulse modulation) of synthetic jets. This technique is shown to shed circulation in a controlled manner during dynamic stall, reducing many of its detrimental effects.
