| Abstract: | The finite volume method and unstructuredgrid as well as SIMPERC arithmetic method are adopted in this paper to simulate numerically the interior flow of a siphon outlet conduit,the validity and reliability of numerical computation method are verified by physical model experiment.Based on the calculation of velocity distribution coefficients of key cross-sections and head loss of the conduit,the hydraulic design level can be evaluated quantitatively.Thus,the prediction of hydraulic characteristics of siphon outlet conduits is realized,the hydraulic design optimization is conducted,and a lot of experimental cost and time is saved. |
