| Abstract: | The flowfield of diffraction of shock wave over a half-diamond cylinder is very complex. In this paper the phenomena of diffraction were investigated experimentally and numerically. The experiments were conducted at UTIAS shock tube and the second-order scheme was adopted to simulate flowfield numerically. Finally, experimental results were competed with numerical simulations. |
