Flow Control Using Plasma Actuators and Linear/Annular Plasma Synthetic Jet Actuators
3rd AIAA Flow Control Conference, 2006This paper investigates the use of dielectric barrier discharge plasma actuators in low Re flow control applications. Three different actuator geometries have been tested: a conventional design using two rectangular strip electrodes (the linear actuator) that produces a nearly two-dimensional horizontal wall jet upon actuation, and two new designs that

Aerodynamic actuation characteristic research of array plasma synthetic jet actuator
2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017An array PSJA is tested in this paper by using high-speed phase-lock schlieren system. The characteristic of the transient flow field is studied. The experiment shows that a series of high-speed blast waves spreads outward after discharge. These blast waves, attenuated to the local sound speed, form a wavefront, which continues to influence the flow ...

Formation and Scaling of Plasma Synthetic Jet Actuators
45th AIAA Aerospace Sciences Meeting and Exhibit, 2007The 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 ...
