Dielectric Barrier Discharge Plasma Actuator Thrust Measurement Methodology Incorporating Antithrust Hypothesis

Abstract: The thrust of the dielectric barrier discharge plasma actuator is the plasma body force minus the wall shear force,and it equals the net induced momentum. Thrust measurement simplicity makes it a good metric of the aerodynamicperformance for active flow control applications. Uncertainty and non-repeatability issues with conventional testsetups motivated development of a novel suspended actuator test setup and a measurement methodology consisting ofa burn-in procedure followed by frequency sca…
