摘要

沉体周围自由表面流动是当前应用流体力学中的一个CFD问题。本文的目的是对自由表面附近沉体周围流动的实验与数值模拟进行比较研究。实验研究了亚临界状态下，雷诺数Re = 3500，弗鲁德数Fr = 0.06时平面通道内的自由表面流动。利用FLUENT软件、RNG k-ε湍流模型和计算自由表面几何形状的流体体积(VOF)模型进行了数值模拟。计算结果与室内实验结果吻合较好。

Free surface flow over the broad — Crested weir

The free surface flow around immersed bodies is a current CFD problem in applied fluid mechanics. The aim of this paper is to present a comparative study between experiments and numerical simulations of the flow around immersed bodies in vicinity of the free surface. The free surface flows in a planar channel were experimentally investigated in subcritical regim at Reynolds number Re = 3500, respectively Froude number Fr = 0.06. Numerical simulations are performed with the FLUENT code, RNG k-ε turbulent model and the volume of fluid (VOF) model for calculating the free surface geometry being used. The computational results showed a close agreement with experimental data obtained in the laboratory for the flow over the broad - crested weir with smooth and patterned surfaces.
