摘要
针对某电站尾水渠实际情况,应用k—ε模型和控制体积法建立了三维紊流数学模型对原设计体型进行模拟,并将计算结果与物理模型试验的测量结果进行比较,验证了三维数值模拟计算的准确可靠性。在此基础上,根据工程的实际需要对尾水渠不同体型进行了流态、流速分布及能头损失的数值模拟,为尾水渠体型优化提供了建议。
According to the actual situation of a hydropower station tail channel,the k-ε model and finite volume method(FVM) are used to establish three-dimensional turbulence mathematical model for simulating the primary designed shape.Comparing the calculation values with the measured values of the physical model experiment,the accuracy and reliability of numerical simulation are verified.According to the actual project requirement,the flow pattern,velocity distribution and energy loss are simulated under the different shape of tail channel,which provides suggestion for shape optimization of tail channel.
