Аннотация:The influence of an insert installed in the discharge initiation zone (on the wall of a rectangular channel) on a high-speed gas-dynamic flow is investigated. The main modes of localization of a submicrosecond volume discharge initiated in a high-speed flow of various speeds (up to 1 km/s) are identified. It was shown that the change in the self-localization region of the pulsed discharge in the flow was associated, first of all, with a change in the structure of the gas-dynamic flow created near the obstacle as a result of a change in the speed of the oncoming flow.
