Airflow characteristic of multiphase plasma aerodynamic actuation

Multiphase plasma aerodynamic actuation is produced when the phases of the plasma electrodes are different. A system of particle image velocimetry(PIV) was established， and the experimental study on the characteristic of plasma aerodynamic actuation with dissymmetrical configuration as well as the velocity of the airflow induced by multiphase plasma aerodynamic actuation was performed by PIV technique. The result indicates that, the spatial structure of the airflow field based on plasma aerodynamic actuation could be accurately reflected with PIV technique. The direction of the injection flow induced by plasma aerodynamic actuation is parallel to the actuator surface, and the velocity of the induced flow increases or the flow field extends while the phases of the plasma electrodes are reg
