Abstract：A mathematical model has been built for the geometric contours of siphon outlet conduit in pumping stations based on the principle of gradual rate,and the general software for hydraulic optimum design has been developed based on the geometrical parameters of outlet passage.The geometric contours of siphon outlet conduit can be drawn quickly.The hydraulic performance of siphon outlet conduit can be predicted through numerical simulation of the internal flow status of the conduit.The optimization models are established on the basis of the hydraulic loss of the conduit as the objective function and the location of the hump section of the conduit as the variable.The results indicate that the closer to the intake the hump sections of the conduit are,the less the hydraulic loss of the conduitis is.It is suggested that the location of the hump section should be close to the intake as much as possible in order to reduce the hydraulic loss.
