摘　　要：通过实验和数值计算模拟了激波（马赫数７．６）绕４０度压缩拐角的流动。实验是在气动中心激波管中完成的，数值模拟采用了层流的Ｎ－Ｓ方程，对无粘项、粘性项和化学源项分别采用了迎风ＴＶＤ格式、中心差分格式和点隐式的方法进行差分离散，计算了平衡与非平衡条件下的马赫反射流动，其数值计算结果与实验结果符合甚好。In the present paper, both experiment and computation onthe reflection of the shock waye of Ms=7.6 from wedge of θ=40° areinvestigated. The experiments are carried out in CARDC shock tube.-Thecomputation of both equilibrium and nonequilibrium Mach reflection folwis based on the laminar full N-S equation in which the inviscid terms,source terms are calculated by second order upwind TVD scheme and apoint-implicit method,respectively. The results of computation are in goodagreement with that of experiment in all flow fields.
