Plasma actuator simulation: Force contours and dielectric charging characteristics

TLDR: In this paper, the force contours produced during dielectric barrier discharge on a plasma actuator were discussed. But the authors did not consider the effect of the dielectrics on the dynamics of the discharge.

Abstract: We have discussed the force contours produced during dielectric barrier discharge on a plasma actuator. There is asymmetry in the direction and magnitude of forces during cathode directed and anode directed discharges. This can be attributed to the difference in the dielectric charging characteristics during positive and negative pulses. Accurate modeling of surface processes on the dielectric is essential to understanding the working of the actuator.
