摘要
为研究闸站枢纽泵站进水流动特性,运用三维湍流数值模拟的方法,模拟了枢纽进水流动形态,对进水回流的形态及位置进行了计算分析。结果表明:枢纽泵站前池流态的主要影响因素为闸站结合部隔流墙及上游河宽与前池宽度的比值;在各种流态改善措施中,前池设置导流墙能取得较理想的整流效果;对于闸站合建枢纽此类侧向进水流动,底坎、底坡等措施整流效果不大。
In order to research the intake water flow characters in sluice-pump station, using the numerical simulation method of three-dimensional flow has simulated the flow pattern in hydrojunction, calcutated and analyzed the flow pattern and position for the circum flunce. The results have shown that the main effecting factors for the flow pattern in forebay were the partition wall in the joint-part of the sluice-pump station and the ratio of river width in upstream to the width of the forebay. In all kinds of improving measures for the flow pattern, installed the deverting wall in forebay can be obtained the ideal effect. For the hydro-junction project of sluice pump station by the side-inflow, it was no any effect for improving flow patter by the bottom sill or bottom slop and so on.
