摘要
对高坝紊流数值模拟中的几项关键技术进行了系统总结,特别是介绍了不规则动边界如自由表面和具有未知底部边界的冲刷坑的模拟跟踪技术、正交与非正交网格生成技术、两相流包括水-气两相和固-液两相紊流模拟中的关键技术,指出紊流数值模拟技术将在高坝水力学问题的研究中得到越来越广泛的应用。
In this paper, the key techniques of turbulent simulation in high dams are summarized, including simulation for irregular moving boundary condition such as predicting the shape of free surface and scouring of riverbed, orthogonal and un-orthogonal mesh generation, two phase flow of water-gas and water-solid, etc. These techniques will be widely used in the high dam hydraulic field.
