OBLIQUE SHOCK WAVE REFLECTION FROM THE WALL [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2015 Regular and Mach (irregular) reflection of an oblique shock wave from the wall is considered. Criteria for the transition from regular to irregular reflection are described: von Neumann criterion and the criterion for fixed Mach configuration. Specific

Approximate Analytical Models of Shock-Wave Structure at Steady Mach Reflection
Fluids, 2021 In this study, we obtain the comparative analysis of methods of quick approximate analytical prediction of Mach shock height in planar steady supersonic flows (for example, in supersonic jet flow and in narrowing channel between two wedges), that are ...

A Study of the Dependence of the Mach Stem Height on the Trailing Edge Height
Fluids, 2021 The Mach stem height is an important parameter in the Mach reflection of steady supersonic flow. Various experimental, numerical, and theoretical works have been conducted to study this parameter in the past. However, much of the established work focuses

Mechanism of hysteresis in shock wave reflection [PDF]
Physical Review E, 2021 This paper reports on the mechanism of the hysteresis in the transition between regular and Mach shock wave reflections. We disclose that, for a given inflow Mach number, a stable reflection configuration should maintain the minimal dissipation.

Reflection of the strahl within the foot of the Earth's bow shock [PDF]
Annales Geophysicae, 2019 The reflection of a fraction of the solar wind at the bow shock to some extent defines the physical properties of what is known as the foreshock, the region where the interplanetary magnetic field has a direct connection to the bow shock.

Shock wave mitigation using zig-zag structures and cylindrical obstructions
Defence Technology, 2021 The present study focuses on the mitigation of shock wave using novel geometric passages in the flow field. The strategy is to produce multiple shock reflections and diffractions in the passage with minimum flow obstruction, which in turn is expected to ...

The shape of incident shock wave in steady axisymmetric conical Mach reflection
Advances in Aerodynamics, 2020 For internal flow with supersonic inflow boundary conditions, a complicated oblique shock reflection may occur. Different from the planar shock reflection problem, where the shape of the incident shock can be a straight line, the shape of the incident ...
