In-tube shock wave compression by piston effect of unsteady jet

Piston dispersive shock wave problem.

The piston shock problem is a classical result of shock wave theory. In this work, the analogous dispersive shock wave (DSW) problem for a fluid described by the nonlinear Schrödinger equation is analyzed. Asymptotic solutions are calculated for a piston (step potential) moving with uniform speed into a dispersive fluid at rest. In contrast to the classical case, there is a bifurcation of shock...

The Development at Cranfield of a Free Piston Compression Shock Tube

SUMMARY The free piston compreeslon shock tube provIdea a simple means of obtaining shock Mach numbers of the order of 30. This paper concerns the design and development at Cranfteld of such a shock tube. The problem6 encountered in evolving a pwton capable of withstanding heavy impacts at the completion of 50s stroke are outlined, and some preliminary shock tube perfonnanoe data given.

Numerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow

Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
