摘　　要：本文采用标准k-ε双方程紊流模型及基于水气两相流的VOF方法,运用FLOW3D软件对闸坝进行数值模拟,得出不同水位下的闸坝泄流能力,以及不同部位的闸室及消力池水面线、流速、压力等重要水力学要素。结果表明数值计算在一定程度上可以达到模型试验的效果。In the paper,standard k-εdual equation turbulence model,VOF method based on water-gas two phase flow, and FLOW3D software are adopted for numerical simulation on gate dam.Gate dam discharge abilities under different water levels,water surface line of gate chambers and stilling basin in different parts,flow velocity,pressure and other important hydraulic elements are obtained.The results shows that numerical calculation can reach the effect of model test to a certain extent.
