Numerical Simulation of Overflow and Energy Dissipation Analysis in Stepped Spillway

Qingfeng Ji

Abstract

The turbulence model is applied to simulate the turbulent overflow of stepped spillway and non-stepped spillway,the VOF(Volume of Fluid) method is used to determine free surface.From numerical simulation,the velocity field of two spillway model are obtained,finally,the article compares the effect of energy dissipation between two spillway,and indicates that the stepped spillway is very well in energy dissipation.
