摘要:
结合泵站弯道引水渠工程设计，应用大型商业软件建立弯道引水渠水流三维数学模型，基于CFD 数值模拟技术，分析了该泵站弯道引水渠水流流动特性。根据该泵站弯道引水渠三维水流水动力学的计算成果可得知，在设计水位下，泵站弯道引水渠水流流线弯曲进入进水池，降低各个机组水流流速均匀性，降低机组工作效率；弯道引水渠曲率半径需要控制在一定范围内，可通过CFD 数值模拟或水工模型试验确定最优曲率半径；弯道引水渠相对于顺直引水渠水力特性较差，非特殊情况，不宜采用；采用弯道引水渠，要延长引水渠顺直段，直至水流流态平稳，流线顺直。本文研究成果对采用弯道引水渠的泵站设计具有一定的参考价值。
Abstract:
Combined with the design of bend channel of pump station，three dimensional mathematical model of water flow in bend channel with large commercial software is established.Based on the CFD numerical simulation technology，the flow characteristics of the water flow in the bend of the pump station are analyzed.According to the calculation results of three dimensional water flow dynamics in the bend channel of the pump station，under the design water level，the flow line of the bend channel of the pump station is bent into the water inlet，which reduces the uniformity of the flow velocity of each pump，and reduces the working efficiency of the pump.The curvature radius of the water diversion canal is needed to be controlled in a certain range.The best curvature radius can be determined by the CFD numerical simulation or hydraulic model test.Normally，the bend channel should not be used because of its bad hydraulic characteristic.If it is used，the straight section should be extended until the flow is stable and streamline along.A certain reference value for the design of the bend channel in pump station is provided in this paper.
