Power consumption, discharge capacitance and light emission as measures for thrust production of dielectric barrier discharge plasma actuators

J Kriegseis, S Grundmann, C Tropea - Journal of Applied Physics, 2011 - pubs.aip.org
A new procedure of determining the time resolved capacitance of a plasma actuator during
operation is introduced, representing a simple diagnostic tool that provides insight into the
phenomenological behavior of plasma actuators. The procedure is demonstrated by
presenting example correlations between consumed electrical energy, size of the plasma
region, and the operating voltage. It is shown that the capacitance of a plasma actuator is
considerably increased by the presence of the plasma; hence a system that has previously …
