Abstract
The development of a pulsed volume discharge with pre-ionization in a non-uniform supersonic air flow near the wedge in the shock tube channel and the gas-dynamic flow that occur after the discharge has been experimentally studied. Plasma configurations that occur near the bottom of the wedge were investigated for the discharge initiated at various stages of an unsteady flow. The self-localization conditions of a volume discharge in the vortex zone behind the wedge are analyzed at the incident shock wave Mach numbers of 2.6–3.5 (at the flow Mach numbers up to 1.50 and a density up to0.15 kg/m3).
