摘　　要：　本文推广了建立在半交错网格基础上的连续性方程压力联系方程方法来计算不可压缩粘性轴对称体内外流问题,整个内外流流场分块生成结构化网格,统一求解。并与建立在交错网格上的有限体积方法计算进行了比较,都得到了令人满意的结果,证明这两种方法在求解包含内外流流场的问题时是高效的。The paper has developed a pressure-linked method of continuity equation based on half-staggered grids to solve simultaneously the internal and external flow over an axisymmetric body, using domain decomposition method to generate the structured grid system of the whole flow area. Additionally, the same problem has been solved successfully by finite volume method, discretizing the equations on staggered grids. The two methods both get satisfactory results, showing their efficiency of solving the given kind of problems.
