摘要
本文针对三维水流特性,引入通度概念处理不规则计算边界,用VOF法追踪自由表面,采用修正的K-ε模型封闭Reynolds方程,分别计算了溢流坝水流及消力池中水跃.计算结果较好地与实验结果符合.
A modified K-εturbulence model is derived and the governing equations of turbulent flow for irregular boundary are developed by analyaing the solid-liquid two-phase theoretical flow model. A partial-cell parameter is introduced to treat irregular boundary. It shows that the calculated results are in good agreement with the experimental data.
