摘要
水力发电厂拦河闸引水口附近的水流流态复杂,且行洪期受泥沙影响较大。通过紊流数值模型对该区域工程整治的三维流场进行了数值模拟,计算结果给出了该区域的三维流速分布,结合泥沙运动特性可预估其工程效益,为相关部门的工程整治方案提供基本数据。
Near the sluice-way door of waterpower work, the turbulent fluent is complicated. In flooding period, the effect of lead water always is influenced by the sediment. In this paper, the 3D simulation of the fluent is taken by the k-ε mathematical model. The distribute of the current speed is given by the calculated results. Combined with the characteristics of the sediment transportation, we could take a rough estimate of the benefits with the reformed projects and give the basic date of the scheme about the reformed projects to the related units.
