Formation and Scaling of Plasma Synthetic Jet Actuators

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
The plasma synthetic jet actuator is a plasma actuator consisting of an annular electrode array separated by dielectric material, with a larger electrode that is exposed to the atmosphere and a smaller electrode embedded on a surface. Under input of high voltage, high frequency AC or pulsed DC, a region of plasma is formed starting from the toroidal ...
