| 摘 要： | 利用实用、高效的泄洪洞整体三维紊流数值模型,对滩坑水电站泄洪洞进行了数值模拟,该模型采用引入VOF方法的k-ε紊流模型,结合通用性强、易扩展的非结构混合网格。为克服网格扭曲给计算精度带来的影响,用一种改进精度的格心格式计算通量,使之具有非结构网格剖分的灵活性,程序的通用性和可扩展性,又有较高的计算精度。数值模拟结果和模型试验数据的对比分析表明,该模型是实用可靠的。

| Abstract: | With 3D mixed element type unstructured grids, the numerical model that can simulate the 3D turbulent flow of spillway tunnel is established in this paper.The volume of fluid (VOF) method and the k-ε two-equation model for turbulent flow are adopted.The 3D Navier-Stokes equations are solved by using an improved cell-centered finite-volume method in order to eliminate the adverse influence of grid quality on stability and convergence speed.The comparison between the numerical results and the experiment data in spillway of Tankeng Hydropower Station shows a satisfactory agreement. |
