| 摘 要： | 采用三维嵌合体网格埋入技术计算复杂外形的流场,这种技术简化了复杂几何外形计算网格的结构,将物理区域分成一系列子域,使每个子域都易于生成网格,并且其流场的计算可根据相应的边界条件独立地求解,在埋入边界上对流动参数进行插值传递子域网格的干扰信息,通过两个流场的耦合迭代计算整个流场的解。

| Abstract: | A three-dimensional chimera grid-embedding technique is used for complex configuration. The technique simplifies the construction of computational grids about complex geometry.The method subdivides the physical domain into regions which can accommodate easily generated grids. Communication among the grids is accomplished by interpolation of the dependent variables at grid boundaries. An chimera grid-embedding scheme is implemented for a C-5A wing/body/pylon/nacelle. Numerical results show that the present algorithm is stable, accurate, and can be used effectively to compute the flow field about complex configuration. |
