| 摘 要： | 为了全面了解坝身泄洪水力学特性,采用基于VOF方法的水气两相流二维紊流数值模型对坝身表孔泄洪进行了计算模拟,得到的坝面压力、水舌入水点等水力特性与1:50比尺的整体模型试验值基本吻合,同时还进一步分析得出了坝后较真实的水舌风场、坝身泄洪的能量损失过程以及水垫塘的水流特性,表明两相流数值模拟是研究坝身泄洪水力特性的有效方法。

| Abstract: | In order to study the characteristic of the flood relief two-phase flow from surface outlet into plunge pool,the volume of fluid(VOF) method was applied to simulate the whole flow field.The distribution of pressure of dam surface fitted well with the experimental data measured on a three-dimension model with a scale of 1:50.The nappe-wind field during flood discharge of a hydropower station and its process of energy loss were obtained by two-dimension numerical simulation. |
