含脱体激波流场的数值模拟仿真

Numerical simulation of the flow field with the detouched shock waves

利用经典的质点网格法进行了含脱体激波的超音速流动的数值模拟，绘出了形象直观的超音速流动图画，且模拟流场中的各项参数与实验符合较好，为今后进一步探讨复杂形状物体的超音速运动提供了基础．

The supersonic flow with detouched shock waves are simulated by means of the classic PIC(particle-in-cell) method. The picture of the supersonic flow is vividly drawn in the paper, and all parameters in the flow field accord well with those obtained in the experiment, thus a foundation is layed for furthering the study of supersonic movements of complicatedlyshaped bodies .
