摘　　要：本文对发射台底面与后挡板之间的喷流流场进行了数值研究。采用迎风的Ｐｅｔｒｏｖ─Ｇａｌｅｔｋｉｎ有限元方法求解欧拉方程。描述了喷流出口处及挡板附近的流场细节。计算结果已成功地应用于导弹发射台的设计。A numerical study of a propulsive jet flow confined by bottom plane and against a flat plate is made. The Euler equations are solved using a Petrov-Galerkin finite element approach with a stream-upwind technique.The flow field details are described in both the jet exit base region and the near region of the opposite plane.The computation results are applied on a missile launching pad successfully.
