Particle image velocimetry is performed in order to analyze flowfield induced by a dielectric barrier discharge plasma actuator. The velocity vector fields are obtained for the two different input voltage conditions; the voltage 3 and 5 kV at the frequency 10 kHz. The obtained flowfields show that the air is accelerated and its speed increase almost linearly over the covered electrode. The amount of momentum induced by the DBD plasma actuator is estimated from the obtained velocity fields, and the estimated values reasonably agree with the previous experiment.
