介绍了孟加拉国达卡市Rampura雨水泵站的工程设计,在工艺设计阶段引入数值模拟和水力模型试验。采用数值模拟手段对泵站进水前池设计方案进行模拟,为工艺设计提供依据。制作1∶6几何比例的实体模型来观察各种工况下的实际流态,判断泵站设计的合理性。本工程将雨水泵站的工程设计与数值模拟和实际模型相结合,为泵站的设计及测试提供了经验及思路。
The engineering design of Rampura rainwater pump station in Dhaka, Bangladesh was introduced. Numerical simulation and hydraulic model test were introduced in the process design stage. The numerical simulation method is used to simulate the design of the inflow pool before pumping station, which provides the basis for process design. Make a 1: 6 geometric model to observe the actual flow in various conditions, to determine the rationality of pumping station design. This project will rainwater pump station engineering design and numerical simulation and the actual model of the combination for the pumping station design and testing provided the experience and ideas.
