Abstract
Research interest in plasma actuator is increasing day by day in the field of fluid dynamics. Various types of plasma actuators are used for various research purposes. In most cases, the plasma actuator is based on a surface dielectric barrier discharge (DBD), the flow is produced between two electrodes mounted on both sides of a dielectric material and can be used in flow control applications due to the momentum transfer from the plasma species to the fluid. This paper investigated floating type DBD plasma actuators in the absence of external flow by means of particle image velocimetry. The electric wind was generated by a single DBD excited by a sine wave of 5 kHz. The induced flow was compared by changing the distance from the leading edge to the actuator position.
