| Abstract: | Stepped spillways have become very important in the flood discharge and energy dissipation.Therefore ,the velocity,pressure and other characteristics of the flow on the stepped spillway should be known clearly.But so far the study on the stepped spillway overflow is only based on the model test.In this paper the stepped spillway overflow is simulated on a Reynolds stress turbulence model.The simulation results are analyzed and compared with measured data and the results are satisfactory. |
