Boundary Layer Separation Plasma Control Using Low-Temperature Non-Equilibrium Plasma of Gas Discharge

The influence of pulsed sliding discharge on the flow separation has been investigated. The high efficiency of pulsed discharge was shown within the velocity range from 20 to 110 m/s. The dynamics of discharge propagation with nanosecond time resolution was obtained. The influence of electrodes geometry was investigated. It was found that discharge affects flow separation while the electrodes were placed in parallel to the gas flow so the streamers propagated perpendicular to the flow. The conclusion was made that main mechanism of plasma influence is the boundary layer turbulization.
