摘要
泵闸枢纽工程是解决城市排水问题的有效途径之一。结合上海朱泖河泵闸工程,针对因结构布置上要满足该泵闸运行条件而产生的较复杂的水流问题,采用三维有限元计算手段模拟了泵闸运行时进出水池的水流状况,与模型试验结果进行对比,数值模拟结论与模型试验结果相符,并提出改善措施解决了因导流隔墙绕流现象导致的进水池水流不均问题。
The pump brake hub engineering is one of the means of solving water drainage in urban areas. Based on the pump brake projects of the Zhumao River in Shanghai. The three-dimensional finite element is used to simulate the water flow in time of the pump brake＇s operation. Numerical simulation conclusions are compatible with experiment results. Some improvement measures have been put forward to solve uneven water flow.
