The influence of plasma actuators material and geometry on the electromagnetic characteristics of the discharge and the specific thrust of synthetic jets

Abstract

It was examined the effect of electrode material on the value of specific thrust of the synthetic jets produced by symmetric actuator. The dependences of specific thrust on the distance between external electrodes for copper, aluminium, nickel and titanium was made. A considerable effect of the shape of the external electrodes on the electric field and current density in the tape drive and the specific thrust of the synthetic jet were investigated. The role of autoelectronic emission on the current in streamers and the value of volume force acting on the stream were also evaluated.
