摘要
本文利用三维标准k-ε紊流数学模型,选择VOF方法追踪自由表面,采用气液两相流计算模型对宽顶堰流场进行了数值模拟,计算结果与试验数据较为吻合。模拟结果表明,数值模拟能够广泛应用于数值模拟带有复杂自由表面的泄水建筑物紊流场。
The Three dimension turbulence model is applied to simulate the turbulent overflow of broad crested weir, VOF method which makes tracks for free surface and air--water multiphase flow model, and the computational results are to fit in with experimental data. The result shows that numerical simulation can be widely used to compute the water release structure turbulent flow with complicated free surface.
