THE PHYSICS AND PHENOMENOLOGY OF PARAELECTRIC ONE ATMOSPHERE UNIFORM GLOW DISCHARGE PLASMA (OAUGDPä) ACTUATORS FOR AERODYNAMIC FLOW CONTROL*

for making available a Pitot tube system. In this paper, we present data on the physics and phenomenology of plasma actuators based on the One Atmosphere Uniform Glow Discharge Plasma (OAUGDP™) that may be useful in optimizing the paraelectrically induced flow velocity. It is shown that the real (as opposed to reactive) power delivered to an actuator is divided between dielectric heating of the insulating panel, and power delivered to the plasma that is available for flow acceleration. The correspondence between the power input to the plasma and the flow velocity is presented, along with a discussion of selecting the RF voltage, frequency, electrode gap distance, and dielectric material that optimizes the induced flow velocity of a single actuator for a given power input to the plasma. Induced flow velocities in air of 5+ m/sec from
