| 摘 要： | 本文研究了在中部带有裙体后向台阶的轴对称体的超声速绕流特性。采用空间推进法数值模拟超声速无粘流场，对于轴对称后向台阶的分离区采用Ｃｈａｐｍａｎ－Ｋｏｒｓｔ理论模型进行处理，计算结果给出了与实验值吻合的物面压力分布以及超声速流场的流动图画。

| Abstract: | A Computational model for predicting supersonic flowfield with separattd subsonic reglon caused bv convex axisymmetric back-ward-facinq step is presented.The model is based upon the supersonic spatial marcliing technique of Euler equations,combined with Chapman-Korst theoretical model.Good agreement between computational results and the experiment data are showed. |
