- W2394913253 abstract "Surface plasma discharges as a possible solution to improve the aerodynamic performances of future aircrafts have generated significant interest. In l abs experiments already demonstrated that non-thermal plasma discharges can overcame some practical problems such as control of separated airflow [1]. When arranged asymmetrically and operated under AC high voltage, a self-sustained and self-limited weakly ionized region is initiated producing a tangential wall jet (‘electric wind’) resulting fro m colliding charge and neutral particles. Like observ ed from traditional mechanical flow control systems [2], plasma actuators driven by burst modulation of the AC carrier signal is more effective to improve the aerodynamic performances. However, the spatiotemporal analysis of the flow produced by a plasma actuator driven by burst modulation has not been detailed. In the present paper a typical asymmetric Dielectric Barrier Discharge (DBD) is investigated. The acquisitions systems allow accessing the timeaveraged and time-resolved produced flow. The effects of the frequencies and the duty-cycles of t he modulating waveform are studied. This study may bring helpful considerations to accurately adjust t he high voltage signal according to the flow control objectives." @default.
