Microplasma actuator for active flow control: Experiment and simulation

Abstract

Dielectric Barrier Discharge microplasma actuator energized at low discharge voltage at about 1.4 kV was applied for flow modification. Due to the microplasma generation, the flow velocity showed different characteristics at various duty ratios of the applied voltage. The observation with the high speed camera showed at various time intervals the modification of the flow due to the microplasma. The numerical simulation of the flow was carried out using Suzen model which is assuming that the electric potential of plasma actuator potential can be split in the potential due to the external electric field and potential due to the charge density of plasma.
