Effect of Duty Cycle on Flow Induced by a Dielectric Barrier Discharge Plasma Actuator in Burst Mode

EasyChair Preprint 2220

Abstract

The periodic vortical flow pattern generated by a burst modulated dielectric barrier discharge plasma actuator in quiescent atmospheric air is presented. The flow field has been studied with the help of smoke flow visualization and time resolved particle image velocimetry techniques. The effect of duty cycle on the behavior of periodic vortex has been presented. The periodic vortex behavior and it's interaction with the remnant vortex have been described with the help of streaklines, vorticity and Q-criterion. The duty cycle alters the vortex growth and vortex core location.

Keyphrases: DBD plasma actuator, Periodic vortex, Plasma actuator, Remnant vortex, Smoke visualization, Starting vortex, burst-mode, flow control
