Some recent applications of plasma actuation include high-speed flow control using localized arc filament plasma actuators,[10] and low-speed flow control using dielectric barrier discharges for flow separation and 3D wake control[11] and sound control[12] and sliding discharges.[13] The present research of plasma actuators is mainly focused on three directions: (1) various designs of plasma actuators; (2) flow control applications; and (3) control-oriented modeling of flow applications under plasma actuation.
