Numerical simulation of hydraulic characteristics on the airfoil-shaped measuring-flume in rectangular canal

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-e 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.
