The effect of electrode material on the efficiency of dielectric barrier discharge

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

“…An increase in the distance between exposed electrodes leads to leveling of the specific thrust of actuators with copper and nickel electrodes. This is explained by the fact that an increase in the distance traveled by near-wall jets before collision leads to greater energy losses due to viscous forces and Joule heat fluxes from heated electrodes [6]. Thus, the positive effect observed under extremal conditions is counterbalanced by increased heat evolution from the surface of electrode.…”
