The phenomenon of pulsed volume discharge plasma and current redistribution based on self-localization in an unsteady flow in a shock tube with 48 x 24 mm cross section is described. It is shown that in the gas-dynamic channel with a parallelepiped-shaped step in the flow behind theshock wave with Mach numbers of 2.8 - 3.5, short-lived plasma channels are formed in the separation zones near the step within 2800 μs.
