CFD数值模拟在沉沙池设计中的应用

The Application of CFD Numerical Simulation in the Design of Desander

以高喜马拉雅地区水电站的沉沙池设计为研究对象,采用Flow 3D进行模拟计算并对多个部位进行优化设计,最终在工程布置调整空间有限的情况下,以工程量增加极少的代价,满足了远超设计标准要求的>0.2mm粒径泥沙95%的沉沙率。

Taking the desander design of the hydropower station in the High Himalaya region as the research object,Flow 3D is used for simulation calculation and optimization design of multiple parts.Finally,under the condition of limited engineering layout and adjustment space,95% of the desilting rate of >0.2 mm grain size sediment far exceeding the design standard is met at the cost of little increase in engineering quantity.
