Abstract

The results of studies of the effect of volume and surface pulse discharges on high-speed gas flow in a rectangular shock-tube channel with a change in the profile (obstacle on the lower wall) are given. A single nanosecond surface discharge or a discharge with preionization induced by the plasma electrodes (combined discharge) was initiated in flow downstream of the shock wave with the Mach numbers Ms = 3.2–3.4. The obstacle determines the distribution of the parameters of flow past the obstacle and the pulse discharge plasma redistribution. The density fields of gas dynamic flow under the experimental conditions are obtained and compared with the discharge plasma distribution. It is shown that the shock-wave effect of the discharge on flow behind the obstacle continued from 25 to 70 μs.
