Turbulence Numerical Modeling of Stepped Spillways Overflow

For numerical simulations of water flow over stepped spillways the commercial computational fluid dynamics (CFD) code Fluent 6.3.26 was used. The steppedspillway has increasingly become an effective energy dissipater. When the hydraulic performance of the overflow is clearly known, the energy dissipation could be increased. To predict the characteristics of flows over stepped spillways, different turbulence models were chosen to enclose the controlling equations. The RNG
