| 摘 要： | 提出了重叠对接耦合分块方法即为隐式求解的块迭代方法。采用自主开发的三维粘性不可压缩流场计算程序对重叠对接与不重叠对接的流场分块求解方法进行了比较研究，并与他人的实验结果进行了比较，符合很好，研究表明，两种算法均能获得收敛解，而利用重叠对接分块法的收敛性优于不重叠对接分块法。

| Abstract: | The domain decomposition method with overlapping grid is presented in this paper as implicit iterative method in algebra systems. A contrastive numerical simulation of three\|dimensional incompressible viscous flows was carried out using our own code with overlapping and non\|overlapping grids,respectively. The results compared well with experiment results in reference\.The research indicated that the convergent results can be reached for the case of two domain decomposition methods; and that the convergence calculated from the domain decomposition method with overlapping grids is better than calculated by the non\|overlapping grid method. |
