摘要: 使用计算流体动力学的方法,对经典的运动激波绕射现象做数值模拟,研究了一类复杂激波反射问题一入射的运动斜激波绕射现象.给出一组运动斜激波绕射波纹壁面的非定常过程的模拟结果。计算结果显示出由运动斜激波绕射诱导的多波干扰产生的复杂流场结构。

Abstract: A new shock wave reflection phenomenon-moving oblique shock diffrection obstacle is investigated. The computation results of normal shock reflection on a wedge is compared with experimental results. Simulation results are given as well for unsteady flow field of moning oblique shock wave diffraction over a wavy wall. A flow field pattern, that's induced by multi shock interaction of oblique shock reflection, is displayed.

Key words: shock wave, unsteady-flow, Flow interaction
