基于VOF模型的团山子溢流坝数值模拟

摘要

This paper introduces the VOF model,combined with the k-ε turbulencemodel,using Fluent soft-ware numerically solving the two-dimensional flow with free surface flow problems.Taking Tuanshanzi water project as an example,It calculated thespillway flow characteristics,which results compared with experimental data showed thatthe calculated values matching well with the measured values;it indicates VOF model can ac-curately track the free surface and the numerical simulation can be used to select the discharge structure de-sign scheme;It study hydraulic characteristicscombined with model test method.%本文介绍了VOF 模型，结合k-ε紊流模型，利用Fluent软件数值求解了带自由水面的二维水流流动问题。以团山子水利枢纽为例，计算了溢流坝内水流流动特性，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吻合较好，说明VOF 模型能够精确地跟踪自由表面，可利用数值模拟对泄水建筑物设计方案比选，结合模型试验的方法，研究其水力特性。
