| 摘 要： | 在边界拟合正交曲线坐标系下,建立了求解变量分别位于同位与交错网格条件下的二维水流数值模拟计算模式。利用实验资料对其进行了验证,同时对两种模式的计算结果进行了比较分析。在运用界面动量插值的条件下,采用同位网格模式对二维流场进行数值模拟可获得较满意的结果。

| Abstract: | Two different 2-D flow models with non_staggered and staggered body_fitted orthogonal curvilinear coordinates system are presented. They are tested by the experimental data of bend. At the same time, the claculating results of two models are compared and analyzed. In conclusion, 2-D flow numerical simulation with staggered body_fitted orthogonal curvilinear coordinates system can obtain the satisfactory result under the condition of momentum interpolation. |
