| 摘 要： | 河道流体数值计算中,为了克服天然河道边界复杂、长宽尺度相差悬殊等困难,基于有势流的等势线和流线的正交机理,利用POSSION方程转换,自动生成了贴合河道边界的正交曲线网格,从而使复杂的河道计算域转变成规则的矩形域,为河流数学模型的数值离散及求解提供了极大的方便。

| Abstract: | In order to deal with complicated boundaries and extremely large difference between length and width dimensions of a natural river course, the othogonal curved nets of a river plane fitting to river boundaries are automatically generated based on the principle of orthogonality of isopotential and flowline by the Poisson equation. This method can transform irregular domains into rectangular domains in calculation, which provides an efficient approach in calculation and discretization of mathematical river model. |
