The aim of this study is to investigate on frequency shift of vortex shedding from a circular cylinder by induced jet using dielectric barrier discharge (DBD) plasma. The electrode of a plasma actuator was mounted on the circular cylinder. A wave form with voltage of 2kV and frequency of 10kHz is applied to the electrode. The forward and backward jets for the main flow direction were induced by electrode arrangements. The time-averaged velocity, turbulent intensity, half width and the vortex shedding frequency in the wake behind the circular cylinder were measured using a I-type Hot-wire anemometer and flow field is visualized using smoke wire method and a digital video camera at a Reynolds number of 1.0×10^3. We discussed that the turbulent intensity of backward jet increases near the circular cylinder, and the half width of wakes decreases and increases using the forward and backward jets. Also, the frequency shift of vortex shedding from circular cylinder using plasma actuators changes with respect to no jet.
