Abstract
The induced jet characteristics of trielectrode(TED) plasma actuators on quiescent air were analyzed. To mitigate the non-uniform discharge nature for sliding discharge on the TED plasma actuator, the notched, saw-tooth electrode was employed for their DC electrode. The observation of the discharge and visualization of the jet revealed that the discharge start from the apices homogenized the density of sliding discharge, resulting the mitigation of two dimensionality of the induced jet of the TED plasma actuator.
