Abstract
The hydraulic characteristics of cylinder measuring flume in trapezoidal channel are simulated by RNG k-ε turbulence model,with VOF method tracking the free surface.The rule of stagnation point water depth,water surface and velocity distribution is obtained.The results of numerical simulation coincide well with experiment data.Stagnation point water depth maximum relative error is 4.11%,minimum relative error is 0.53%.The research showed that,numerical simulation is an available method,and its calculation precision can satisfy the demand of discharge measuring equipment.关键词
