Dielectric barrier discharge plasma actuators (DBDPAs) have been developed for active flow control devices. However, it is necessary to reduce ozone produced by DBD toward practical applications using DBDPAs. In this study, variations of ozone concentration, flow velocity, power consumption were investigated by changing exposed electrodes of DBDPAs. Two exposed electrode prototypes were prepared spantype with exposed electrode width of 0.1 mm, and normaltype with width of 5 mm. It was found that spantype shows lower power consumption and higher flow velocity than that of normaltype at Vpp 4.06.0 kV. Ozone concentration of spantype higher than normaltype at Vpp 4.08.0 kV. In addition, it was confirmed that catalyst located in downstream from the exposed electrode can reduce ozone concentration between 18 and 42 without affecting the induced flow.
