| 摘 要： | 基于Ｅｕｌｅｒ方程，采用高精度、高分辨率的ＧＲＰ有限差分法及算子分裂技术，对激波通过孔板系统的传播、绕射和反射，以及诱导的流场进行了数值研究。计算结果清楚地给出了激波传播、绕射、反射、及相互干扰的复杂流场结构。与实验结果比较，早期两者吻合较好，后期由于湍流发展的影响，必需考虑粘性修正。

| Abstract: | Basing on the Euler Equations,we adopt the high resolutionshock capture GRP scheme and the technique of operator splittingi to simulate the propagation of planar shock wave through a baffle system andits induced flow field.The numerical result shows clearly the propagations,diffraction,reflection and interaction with each other of shock waves. Goodagreement was obtained between the interferograms and the numerical simulation in the early period,later,due to the influence of the turbulence,viscous effect should be concerned. |
