On reflection of shock waves and shock-wave configurations

Technical Physics Letters, 2008
A new approach to the problem of unsteady reflection of shock waves is proposed. It is shown that the type and parameters of the shock wave reflection configuration depend on the type of an object (single shock versus shock-wave configuration) incident on the reflecting surface.

The Normal Reflection of Shock Waves

Physical Review, 1947
The problem of the normal reflection of a shock wave is solved by an approximate analytical integration of the hydrodynamical equations. The solution given here leads to nearly the same numerical results as an exact method, based on a graphical integration of the hydrodynamical equations, which has been described by Chandrasekhar. A method of computing

Standing Shock Formation in a Non-reflected Shock Tube

2012
Pilot tests have been performed on a shock tube to create a standing shock for the study of radiation in shock layers, by the addition of a ‘deceleration’ tube at the exit of a shock tube. Preliminary results at an enthalpy of 43 MJ/kg indicate that a stable standing shock can be formed, and can give a much larger slug of shock heated gas than can be ...

Multiple Shock Reflection in Corners

Journal of Applied Physics, 1954
When a shock is incident upon a corner from either the concave or convex side it is reflected by the walls forming the corner and diffracted at the edge. The mathematical problem corresponding to this phenomenon has not been solved analytically except in the following limiting two-dimensional cases: a weak (acoustic) shock incident on any corner ...

Transonic shock and supersonic shock in the regular reflection of a planar shock

Zeitschrift für angewandte Mathematik und Physik, 2008
We study the regular reflection problem of a planar shock. The criterion of regular reflection of a planar shock for polytropic gases is given, which is the expression of critical angle of incidence \(\alpha_e αe) is also given. When the angle of incidence is greater than or equal to the sonic angle αs, the reflected shock is a transonic shock ...

Shock reflection and oblique shock waves

Journal of Mathematical Physics, 2007
The linear stability of steady attached oblique shock wave and pseudosteady regular shock reflection is studied for the nonviscous full Euler system of equations in aerodynamics. A sufficient and necessary condition is obtained for their linear stability under three-dimensional perturbation. The result confirms the sonic point condition in the study of

Shock Reflection Probe for wind tunnel calibration and investigation of wall-reflected shocks

12th Applied Aerodynamics Conference, 1994
A wind tunnel test device, called the Shock Reflection Probe (SRP), was designed to provide direct measurements of the characteristics of tunnel wall-reflected shocks. The SRP was tested in three different wind tunnels in a 1993 test program to determine the suitability of various wind tunnels for low supersonic testing of a High Speed Civil Transport (

Bifurcation of a reflected shock wave in a shock tube

1992
The problem of shock bifurcation observed for a reflected shock interacting with a boundary layer is investigated both experimentally and numerically. The process has been visualized by means of color schlieren photographs that clearly show the characteristic wave pattern.
