Flow Characteristics Induced by Periodic-Pulsed Plasma over A Conical Forbody
A pair of plasma actuators is added behind the original plasma actuator pair over a 20 conical forefody to extend the angle of attack range for lateral control. Flow induced by the additional actuator in a still air chamber with one atmosphere pressure is investigated using a two-dimensional particle image velocimetry. The effects of pulse duty ratio and pulse frequency on the induced maximum crossflow velocity and maximum axial vorticity are compared with those of steady discharge. To extend the angle of attack range for the lateral control, an additional pair of SDBD is introduced on the forebody tip behind the original SDBD pair, and periodic pulsed SDBD technique is employed to enforce the momentum transfer in the plasma actuator and to save the input power of the plasma actuation. In this paper, tests of a modified model in air at atmospheric pressure is performed. Particle image velocimetry (PIV) is used to measure the flowfield near the cone surface.
