摘　　要：运用自适应八叉树结构直角网格 Euler算法对舵的流场进行了模拟。与无鼓包的舵相比较 ,带有鼓包的舵其气动特性 ,尤其是阻力有所变化。给出了直角网格生成方法以及 Euler方程解法。结果显示 ,本算法很准确地捕捉了激波 ,真实地模拟了该流场。在此基础上讨论了鼓包及其位置对舵的气动特性的影响。A computational study for the three-dimensional inviscid flow around a fin with a bulge has been conducted based on the Cartesian grid method and Euler solver. Compared with the fin without bulge, the aerodynamic characteristics of the fin with bulge are changed, especially for the drag. This paper explains the general issues of the grid generation and Euler solver. The computational Mach contours agree well with the corresponding experimental ones. The effects of the existence and position of a bulge on the aerodynamical characteristics of the fin have been discussed.
