多電極プラズマアクチュエータによる気流剥離制御における駆動条件の影響

抄録

Effects of DC voltage for the flow control performance using tri-electrode (TED) plasma actuators was analyzed in wind-tunnel experiments. The jet from TED actuator is increased (DBD) or changed direction (SD) compared with the jet of SDBD plasma actuator. In low speed wind-tunnel tests of separation control on the NACA0012 airfoil at Reynolds number at 6.0×10⁵, the plasma actuator was mounted on the leading edge of the airfoil. The experimental results show that the TED actuator has advantage in the flow control performance compared to the SDBD plasma actuator. On the other hand TED-DBD and TED-SD do not have many difference.
