Experiments are performed on a 82.5 sweep flat-plate delta wing combined with a dorsal fin of height 0.6 of the wing semi-span at Reynolds number based on the wing root chord of 3.32×105, in which a pair of small and short dielectric barrier discharge plasma actuators are employed at the wing leading edge near the apex of the wing to effect flow control. Measured pressure distributions over the...

Dielectric Barrier Discharge (DBD) plasma actuators with an asymmetric, straight edge electrode configuration generate a wall-bounded jet without moving parts. Mechanistic description of the interaction between Coulombic forces and fluid motion as function DBD parameters remains unclear. This paper presents experimental investigation actuator, including electrical current associated microdischa...

A study using plasma port single-pulsed discharge is performed on the flow control of asymmetrical vortices over slender conical forebody. The different circumferential steady and unsteady pressure distributions are measured in the wind tunnel test. At the same time, the local side force, the increment of local side force and the overall side force and moment are calculated with the circumferen...
