Atmospheric-pressure dielectric barrier discharges for aerodynamic flow control are investigated. The properties of the plasma discharge during positive and negative half-cycles of the driving voltage are studied experimentally and numerically. The simulations are performed in nitrogen. It is shown that during the positive half-cycle the plasma operates in the streamer mode, whereas the negative half-cycle is characterized by a glow-type discharge. The computational results are compared with experimental optical measurements and found to be in good agreement.
