Abstract

In this paper, focusing of a toroidal shock wave propagating from a shock tube of annular cross-section into a cylindrical chamber was investigated numerically with the dispersion- controlled scheme. For CFD validation, the numerical code was first applied to calculate both viscous and inviscid flows at a low Mach number of 1.5, which was compared with the experiment results and got better consistency. Then the validated code was used to calculate several cases for high Mach numbers. From the result, several major factors that influent the flow, such as the Mach number and the viscosity, were analyzed detailedly and along with the high Mach number some unusual flow structure was observed and explained in detail.
