- Аннотация: The spatial structure of a supersonic flow with an oblique shock wave is studied experimentally during nanosecond surface sliding discharge initiation in a discharge chamber of a shock tube. An inclined shock wave was generated in a supersonic flow around a small obstacle on the lower wall of the channel. A surface sliding discharge was initiated on the upper wall of the discharge chamber directly in the region of interaction of the inclined shock wave with the boundary layer. High-speed shadowgraphy visualization of the flow field was carried out with a frequency of up to 150,000 frames per second at Mach numbers of flows up to 1.70. The discharge characteristics was recorded at different stages of flow and showed dependence on the type of interaction of the oblique shock wave with the boundary layer. It is established that the shock wave dynamics from the discharge depends on the discharge mode and the flow Mach number. According to the digital shadowgraph image processing, the shock waves generated by the discharge affects the shock-wave structure of the flow during ~ 100 μs.
