用ＮＳ方程数值模拟了可压缩流向涡和激波轴对称相互作用现象．数值模拟包括定常和非定常两种情况，计算结果分别与相应的实验进行了比较．结果表明数值模拟成功地捕捉到了激波和旋涡相互作用过程中发生的激波波面变形，激波振荡，涡核变大以及激波波后出现驻点、回流区等流场特征．提出了判断流向涡与运动激波相互作用中旋涡破碎的准则
The NS equations are used to simulate the symmetric compressible flow and shock axis. Numerical simulations include two cases, stationary and non-stationary, and the results are compared with the corresponding experiments respectively. The results show that the numerical simulation successfully captures the shock wave surface deformation, shock oscillation, vortex core enlargement, and the stagnation point, back flow zone and other flow field characteristics after shock wave interaction. The criterion for judging vortex fragmentation in the interaction between flow vortex and moving shock wave is proposed
