Flow Control Technology using Non-thermal Plasma

Active flow control technology using the effect of momentum addition by non-thermal plasma has extensively been investigated in the region of aerodynamics especially aeronautics. The plasma flow control device consists of discharge electrodes set on a object surface and a high voltage power source. The advantages of this technique are its ability to induce very thin flow inside the boundary layer, rapid response using electrical control, and the mechanical failure-free resulting from its simple configuration. In this paper, the mechanism and features of the plasma flow control and its applications are reviewed.
