Shock Wave Reflection From a Wedge in a Dusty Gas

International Journal of Multiphase Flow, 2004
The present paper contains a detailed study of shock wave reflection from a wedge placed in various suspensions. In past works, the incident shock propagated initially in pure gas and the suspension started only at the leading edge of the deflecting ...

Regular Versus Mach Reflection for Converging Polygonal Shocks

Shock Waves, 2007
The onset of Mach reflection or regular reflection at the vertices of a converging polygonal shock wave was investigated experimentally in a horizontal annular shock tube. The converging shock waves were visualized by schlieren optics.

Potential Theory for Shock Reflection by a Large-Angle Wedge

Proceedings of the National Academy of Sciences of the United States of America, 2005
When a plane shock hits a wedge head on, it experiences a reflection, and then a self-similar reflected shock moves outward as the original shock moves forward in time.

Reflection of a Shock Wave at a Surface

The Physics of Fluids, 1966
A new finite difference method is employed in obtaining numerical solutions for the complete Navier-Stokes equations. The physical problem treated is the time-dependent propagation of a one-dimensional disturbance, which is produced by the forward motion of a piston through a compressible, viscous, thermally conducting, perfect diatomic gas and its ...

Weak shock reflection

Journal of Fluid Mechanics, 2000
Summary: We present numerical solutions of a two-dimensional inviscid Burgers equation which provides an asymptotic description of the Mach reflection of weak shocks. In our numerical solutions, the incident, reflected, and Mach shocks meet at a triple point, and there is a supersonic patch behind the triple point, as proposed by Guderley for steady ...

Strength of Reflected Shock in Mach Reflection

Journal of the Aeronautical Sciences, 1951
which means that along these lines of constant w the displacement of the locus of jco is proportional to the change in gain. Similar results are obtained if we let Kx be constant and vary K2. I t is now possible by simple construction to obtain the stability diagram for any combination of Kx and K2 after we have computed and plotted four loci.
