Keywords: flow separation control, dbd plasma actuator, naca0015 wing, cfd

Flow-fields around an airfoil changing the directions of induced flow of DBD plasma actuator are numerically simulated with iLES method, and the mechanisms of separation control between the two cases are discussed. The results implies that two types of actuation have different ways of transition process.
