Spatially Distributed Forcing and Jet Vectoring with a Dielectric Barrier Discharge Plasma Actuator

Abstract

investigated. By pointing two plasma actuators at each other, an inverted impinging jet can be created as a result of the two independent jets colliding. By altering the strength of one of the jets relative to the other, the angle of separation can be changed. PIV data was taken to show the effects of altering the voltage (strength) applied to one of the actuators, relative to the other. It was found that with this method, jet vectoring could be achieved. The angle of the jet could be controlled a full 180 degrees through small changes in the voltage applied to the electrodes.
