Refraction of Oblique Shock Wave on a Tangential Discontinuity

The refraction of an oblique shock wave on a tangential discontinuity dividing two gas flows with different properties is considered. It shown that its partial reflection occurs the exception geometrical diffraction shock. Another shock, expansion or weak coincides Mach line can act as reflected disturbance. This study focuses relationships define type and parameters. domains configurations various types discontinuities, including characteristic patterns rarefaction wave, are analyzed. existence structures disturbance, boundaries between them, defined. parameters one solutions exist for refraction. Each domain mapped by regard to number, ratio specific heat capacities intensity refracted wave. conditions regular formulated, defined gases. Refraction phenomena in engineering problems (hydrocarbon gaseous fuel combustion products, diatomic gas, mixture oxygen hydrogen, etc.) discussed. result be applied modeling processes occur supersonic intakes rotating stationary detonation engines. derived used other researchers check quality numerical methods correctness experimental results.
