概要 |
The purpose of the present paper is to report the numerical analysis of diffracting shock wave around a sharp-edged corner. The unsteady and nonviscous two-dimensional equations are solved with the p...iecewise liner method (PLM). The calculated results show that the diffracting shock waves around a corner have been classified into four types. Namely, they are normal, kink, Mach reflection and regular reflection types. The relation between the third shock wave and the vortex has been discussed. Furthermore, the calculated distribution of the pressure along a wall agrees with the experimental data, and the stagnation point on a wall has been observed.続きを見る
