摘要
详细介绍了VOF模型及其应用方法,结合k-ε紊流模型和分段线形方式构造界面的方法,数值求解了带自由水面的三维水流流动问题。以大型水工建筑物溢洪道内水流流动为例,计算了溢洪道内水流流动特性,并将计算结果与实验数据进行对比,结果表明计算值与实测值相吻合,说明VOF模型能够精确地跟踪自由表面,适用于溢洪道等大型水工建筑物内的水流流动的数值模拟。
The VOF model and its method of the application are presented in this paper. Three-dimensional free surface flow is solved numerically by using k-ε turbulent model and piecewise linear interface construction. As an example, the water flow characteristics are analyzed in the hydraulic building-spillway. The calculated results are agreement with the measured data. It shows that VOF model can be used to track the free surface flow and applicable to numerical simulation of the water flow in the spillway.
