The paper investigates the dynamics of a new multiple bipolar multiple Dielectric Barrier Discharges （DBD） actuator using in large-scale flow control. Particle image velocimetry experiments are performed to characteristic the effectiveness of the multi- ple bipolar DBD plasma actuator. The results show that the mutual interaction between the electrodes, one major disadvantage of traditional DBD characterized by reverse discharge can be entirely avoided, and a constantly accelerating electric wind ve- locity can be obtained by using the new multiple bipolar DBD plasma actuator.
