It was investigated the change of the jet flow by using plasma actuator by changing the direction of the plasma induced flow. It was using nozzles equipped with two types of PA with forward flow (Type A) and back flow (Type B). When the duty ratio was 50%, for Type A and Type B, the fluctuation due to plasma induced flow was able to give the most stable fluctuation near the nozzle exit. In Type B, when the duty ratio = 10%, the velocity fluctuation due to the induced flow is weak. In the case of duty ratio = 90% the amplitude of the fluctuation was unstable. When duty ratio = 50%, the most stable fluctuation could be given.
