Abstract
The aim of this study is to investigate on vortex behavior behind a circular cylinder by introducing jet with dielectric barrier discharge (DBD) plasma. The electrode of DBD plasma was mounted on the circular cylinder. A constant AC wave with voltage of 2kV and frequency of 10kHz is applied to the electrode. The forward and spanwise jets to the main flow direction were induced by electrode arrangements. The flow behavior behind a circular cylinder is measured by hot-wire anemometer and visualized by a high speed video camera at Reynolds number of 1.Ox1O^3. We confirmed the flow structure in the wake and the vortex behavior using the plasma actuators.
