摘要 为了提高泵闸工程工作的稳定性和高效性,采用计算流体动力学方法,以设计参数作为控制条件,运用Fluent软件对某泵闸工程进行了数值模拟计算和分析,并对闸门附近的结构进行了优化.结合河道过流特点,建立了断面有效过流面积率和过流均匀度两个表示过流断面水流流态的公式,并以此作为数值模拟优化的目标函数,对泵闸结构进行了优化.通过数值模拟,分析了引、排水工况下的水流及流场分布规律,分析了实际闸门附近的水流动特性和过流情况,分析了内河侧“S”形转弯对工程水流的影响.通过整体水工模型试验,对改造后的消能设施进行了论证.结果表明,改造后的内外河最大流速均小于0.6~0.8 m/s,且河道的有效过流面积率和过流均匀度均大于0.75.

Abstract: In order to raise stability and high effectiveness of pump and sluice gate engineering, the project on a pump and sluice gate works was carried out by an analysis of numerical simulation, and the structure near the sluice gate was optimized depending on the design parameters as a control condition and using Fluent software by computational fluid dynamics methods. Combining the river transflux features, effective transflux area rate and transflux uniformity were set up, which were two formula expressing flow patterns. Using two formulas as the objective of a numerical simulation and optimization function, the pump and sluice gate structure was optimized. The water current and flow field distribution at drawing and drainage conditions were analyed, and the water flow circumstance and transflux near the gate as well as the effect of “S” turn at the inland river side on the water current were investi gated. The results show that the maximum velocity modified of the inner and outer river area is less than 0.6~0.8 m/s, and the effective transflux area rate and transflux uniformity are greater than 0.75.
