Popis: | The aerodynamic performance of an AC powered dielectric barrier discharge (DBD) plasma actuator immersed in pure oxygen and also in O2 + noble gas mixtures is presented in terms of actuator's discharge structure and momentum coupling to the surrounding gas. At various gas pressures the impulse imparted to the freely-moving actuator body and its transient motion as a function of the applied voltage from 8-24 kV at f = 200 Hz is determined using laser interferometry. The present E/N results show that with increase of oxygen content the momentum coupling is better, especially in the negative species dominated forward discharge phase. |
