Abstract：Toaddressisuesarisingfromchaoticwaterflowduetounreasonablepumpingstationoperationandinsuficienforebay design，thisstudytooktheYanhuangdingpumpingstationasatypicalcase.NumericalsimulationsusingFLUENTsoftwarewere conducted toexaminediferentforebaypaternsbasedontheRealizableturbulence modelandtheEulerianmultiphaseflowmodel. Theinfluencesofdiferentdifusionanglesanddiffrentumberofoperatingpumpingstatinsontheflowfieldstrucureinthefrebay were expounded. The results show that： ① As the diffusion angle increases，the number of vortices in the forebay flow rises from one to two.At diffusion angles of 25∘ and 30∘ ，the vortex area occupies less of the forebay inflow，resulting in a more stable flow field. ② （204号 Reducing thenumberofoperatingpumpingstationsfromfivetotwodecreases thevortexareaintheforebafrom31.42mto0.15 m2 ，withoptimalforebay flow achieved when operating pumping stations 3# and4#.Theresearch resultscan providereferenceand guidance for the design and renovation of similar pumping stations.
