Approximate modeling of the flow structure in a $\lambda$-shaped pseudoshock
A. E. Medvedev Khristianovich Institute of Theoretical and Applied Mechanics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk, 630090, Russia
Abstract:
An approximate analytical model of the flow structure in a plane $\lambda$-shaped pseudoshock consisting of a viscous boundary layer and an inviscid core flow is proposed. It is assumed that the boundary layer edge is a streamline with a specified pressure distribution along the channel and that the flow in the pseudoshock consists of an input segment (Mach reflection of an oblique shock wave) and a sequence of internal segments with an identical structure (shock train). Comparisons with experimental data and results of numerical calculations are performed. It is shown that the model provides a sufficiently accurate description of the pseudoshock flow structure.
Keywords:
pseudoshock, gas dynamics, shock waves, compression wave, expansion wave.
