摘要
微波自喷管口出射到低压滞止大气中所形成的流场可简化为轴对称非定常流动问题．本文采用二阶精度迎风ＴＶＤ格式对膨胀不足超音速自由射流进行了数值模拟，并获得令人满意的时间相关解．
When a shock wave propagates into a quiescent atmosphere of low pressure from a nozzle orifice, the flow can be simplied by solving a axisymmetric unsteady flow problem. In this paper second order accurate upwind schemes in total variation diminishing (TVD) type is employed for numerically simulating underexpanded supersonic free jet. A satisfactory time-dependent solution has been achieved.
