摘要
双向贯流泵泵站进(出)水池流道的设计是整个泵站设计的重要组成部分.为了优化水力设计,基于雷诺时均方程和标准k-ε模型,在压力和速度耦合的情况下,采用SIMPLEC算法,对双向贯流泵泵站进(出)水池流道内三维不可压缩湍流流场进行模拟,揭示了流道内部的流动形态.研究结果为优化设计提供了依据.
Design of the forebay（outlet sump）-watercourse of pumping station is an important part of the whole pumping station design,To optimize the hydraulic design of forebay （outlet sump）-watercourse of pumping station, based on the solution of the Reynolds average N-S equations and the standard turbulent model, numerical simulation on three dimentional incompressible turbulent flow-field of the forebay（outlet sump）-watercourse of pumping station with bidirectional tubular pump has been carried out by pressure-velocity connection algorithm with SIMPLIC.The inner flow status is uncovered, the research results provide gist for design of forebay（outlet sump）-watercourse of pumping station with bidirectional tubular pump.
