Poor flow parttern always happens in the forebay of side-inlet pumping station.In order to improve the flow parttern,a side-inlet pump station has been studied by using the SSTk-ωturbulence model in Fluent.A best scheme of diversion piers layout is obtained by qualitative and quantitative analysis;therefore the flow parttern is improved remarkably.The results indicate that due to the flow parttern is not symmetrical in side-inlet pumping station,the scheme of diversion piers should be arranged according to ...
