摘　　要：针对开敞式进水池水流流态问题建立了相应的概化模型,采用数值模拟方法研究了喇叭管中心与后墙距离、悬空高度和淹没深度对进水池水流特性的影响,从水力学角度提出了泵站开敞式进水池的优化体型和最佳工作水位的概念。研究结果可为泵站设计和泵站技术改造提供理论依据。According to the problem of the flow characteristics in the open inlet sump, this paper establishes the gen- eralized model. Numerical simulation method is used to study the influence of the distance between the center of bell mouth pipe and the back wall, hanging height and submerged depth on the flow characteristics of inlet sump. Optimization shape and the concept of optimal water level for open inlet sump of pump station are put forward from the aspect of hydraulics. The result provides theoretical basis for design and technique improvement of pump station.
