Аннотация:New effects of plasma redistribution shock wave (𝑀=2.8–3.4)diffraction onan obstacle at flow ionization with pulse volume discharge are presented. The obstacle has size 48.0×6.2х1.9mm3and consist offorwardfacingand backward facing stepson the wall. Localization of thenanosecond combineddischarge plasma (with pre-ionization in the volume)in non-stationary gas flow was visualized with plasma glowimaging. It is shown that the discharge images visualize flow evolution structure, mainly -zones of reduced density.Image arecompared with 2D CFD simulation.
