セラミック平板プラズマアクチュエータにより誘起される流れの計測

抄録

Measurement of flow induced by ceramic plate Dielectric Barrier Discharge (DBD) Plasma Actuator (PA) is conducted by using 2D2C particle image velocimetry in the windless situation. Velocity distribution in the streamwise direction and the wall-normal direction and the maximum induced flow of PA are calculated by using image processing. Effects of the applied frequency and the applied voltage on the maximum induced velocity of PA are investigated. The induced flow is widely observed along the wall and a sink flow also observed on the electrode. The effect of frequency on the maximum induced velocity is small, while the effect of voltage on the maximum induced velocity is large. The maximum induced velocity of the ceramic PA is confirmed up to approximately 1.4 m/s.
