This study aims to improve the heat exchange performances of heat radiator fins by generating ionic wind on the fin surfaces. The ionic wind generator investigated in this study consisted of a glass plate, a discharge electrode, a bias electrode, and a ground electrode on the back of the glass plate. Dielectric barrier discharge (DBD) was generated by applying AC high voltage of around 14 kHz between the discharge electrode and the ground electrode. Flow velocities were known by measuring dynamic pressure with a glass capillary tube. Test results showed that flow velocity reached a maximum at 4 mm downstream from the edge of the discharge electrode, whereas DC electric field existed until 5 mm downstream of the edge. It suggested the influence of staying air on the bias electrode.
