Integrated Dielectric Barrier Discharge Plasma Actuator (DBD-PA) can accelerate induced flow successively by electrohydrodynamic force and it is expected to generate stronger airflow than single type DBD-PA. In recent research, it has been found that the induced flow becomes stronger as the number of electrodes of integrated DBD-PA increases, however, not been verified how strong an induced flow can be generated. Therefore, the basic performance of annular integrated DBD-PA is investigated in this study to verify the performance potential of integrated DBD-PA. The annular integrated DBD-PA used in this study has eight rows of electrode pairs arranged on the surface of an acrylic cylinder and it can successively accelerate induced flow along the cylinder circumference. We carried out induced flow velocity measurement by PIV technique and power consumption measurement via V-Q Lissajous method to evaluate the performance of annular integrated DBD-PA. As a result, it is found that induced flow velocity increased by 60 – 140% and power consumption per electrode unit increased by 73 – 238% compared with single electrode type DBD-PA.
