摘　　要：采用VOF方法与标准k-ε紊流模型相耦合,对矩形农渠中三种不同收缩比的机翼形量水槽进行三维数值模拟,并将渠道下游断面水深、过流流量等数值计算结果与物理模型试验结果进行对比,结果表明,二者吻合得较好,从而证明采用三维CFD数值模型对实体模型内部流场的模拟是可靠的,为今后机翼形量水槽的深入研究和优化设计提供了新的方法和依据。By means of conducting 3D numerical simulation on airfoil-shaped measuring-flume of 3 different contraction ratios in rectangular canal resorting to combination of VOF method and standard k-ε turbulence model,and comparing the numerical calculation results like downstream water depth at cross section,flow etc with physical model experiment,from which it can be seen that these data can match each other well,so the reliability of this kind of method to simulate the physical model internal flows is proved accordingly,and therefore the new concept can be referred to for further research and design optimization on air-foil-shaped measuring-flume.
