摘　　要：原先的试验以物理模型为基础,布置模型的测点,利用EZ-Analyst噪声与振动分析软件和数据统计软件,得出一定结论,但是试验存在一定的局限性。本研究将计算流体力学与计算声学相联系,对WES堰的消力池水噪声场进行模拟。借助已完成的物理模型成果,选取3种已完成的WES堰物理模型试验的工况进行数值模拟,通过建立模型,设置CFD边界条件,得到了WES堰模型的水位流态、流速、噪声值的模拟结果。计算结果与物理模型试验结果基本吻合。Based on the physical mode,the measurement points are laid out,EZ-Analyst noise and vibration analysis software and statistical software are used,some conclusions have been drawn,but there are some limitations of the test,this study will link computational fluid dynamics to calculation of acoustic,for WES weir stilling pond noise field simulation.With the results of the completed physical model,three kinds of WES Weir physical model tests have been done to simulate the working conditions,through the establishment of the model,the CFD boundary conditions are set,the simulation results obtains WES weir flow state level model,the flow rate,the noise value.The results with the physical model test results are basically consistent.
