%X In combination with the design of campaniform inlet duct in a certain pumping station of the East Line of South-to-North Water Transfer Project(SNWTP),three different shape suction chamber hydraulic models and experimet apparatus were designed for testing on hydraulic loss.Considering different suction chamber¡äs shape,on the condition of well-distributed flow and offset flow,the Reynolds time-averaged Navier-Stokes equations with RNG turbulent model and SIMPLER algorithm were studied to simulate the three-dimensional internal flow of the inlet duct.The conclusion is that the "¦Ø" shape suction champer has excellent hydraulic characteristic in different inlet flow conditions.Its hydraulic loss is small and velocity-averaged streamline angles on special cross sections are approximately 90¡ã.It is for an idealshape suction chamber of campaniform inlet duct.pumping station;campaniform inlet duct;hydraulic experiment;CFD
