The flow gradients in the vicinity of a shock wave for a thermodynamically imperfect gas

Abstract: Supersonic vortex plane and axisymmetric flows of non-viscous non-heatconductive gas with arbitrary thermodynamic properties in the vicinity of a steady shock wave are studied. The differential equations describing the gas flow exterior to the discontinuity surface and the dynamic compatibility conditions at this discontinuity are used. The gas flow nonuniformity in the shock vicinity is described by the space derivatives of the gasdynamic parameters at a point on the shock surface. The parameters are the gas … Show more

Условие A 15 = 0 в (3) определяет единственную на каждой ударной поляре интенсивность J p скачка уплотнения, при которой геометрическая кривизна скачка не оказывает влияния на локальное значение неизобаричности за ним (так называемую точку постоянного давления). Интенсивность скачка уплотнения в этой точке…”

“…In the recent 15-20 years, a classification of triple configurations [1,2] was developed, their parametric analysis was obtained [2][3][4][5][6], configurations with special properties of individual shocks [4] and extreme ratios of flow parameters on both sides of the emanating slipstream [4,7] were found and studied, and the obtained solutions were generalized for triple configurations of propagating shock waves [8]. Possible additional studies in this direction in the near future can cover the problems of performability of triple configurations forming at Mach reflection with a negative inclination angle of the reflected shock [7,[9][10][11][12][13] or the analysis of differential characteristics of the flowfield applying the dynamic compatibility conditions [2,14].…”
