Abstract: Plasma Synthetic Jet (PSJ) actuators are a type of flow control device which generates high-temperature and high-speed zero-net mass flux jets using gas heating and pressurization of arc discharge in a semi-closed chamber. With advantages of high jet velocity, strong boundary layer penetration ability, fast response, wide actuation bandwidth and no moving parts, this device shows promising applications as a novel active flow control actuator. This paper presents a review of the recent progress in the research on plasma synthetic jet actuators. The optimization designs of plasma synthetic jet actuator systems for improving control authority, increasing energy efficiency and expanding environmental adaptability are summarized, the innovative research methods used in the investigations introduced, and the energy efficiency characteristics and the influence of parameters of the actuator presented. The applications of plasma synthetic jet actuators in various situations such as crossflow interaction, flow separation control, shock control and control of shock wave/turbulent boundary layer interaction are then reviewed. The interaction mechanisms between plasma synthetic jet and crossflow, separation bubbles and shock waves are discussed, followed by the analysis of the effects of momentum injection, blast waves and local heating of plasma synthetic jet in active flow control. The research trends are finally discussed.

Key words: plasma aerodynamic actuation, synthetic jet, plasma synthetic jet, active flow control, energy efficiency, flow separation control, shock wave control
