【摘要】 在水利水电建设中,对于溢流式面板坝,一个重要的问题就是溢洪道的消能,采用不同的消能方式将表现出不同的水力学特性。利用处理复杂自由水面的体积流体分析(VOF)方法和k-ε方程紊流数学模型对光滑式、台阶式两种形式上的水流进行数值模拟研究。更多还原

【Abstract】 In construction of water conservation and hydroelectric project,regarding to the overflow concrete face rock-fill dam,an important question is the energy dissipation of the spillway,which use the different way will display the different hydraulics characteristics.In this article,VOF method is applied to track the complex flow surface and RNG k-ε turbulent model is adopted to simulate the flow current on the two kind’s stair type of smooth spillway and stepped chute spillway.更多还原
