Effect Of Pooled and Flat Stepped Spillway on Energy Dissipation Using Computational Fluid Dynamics

The goal of this research was to determine the impact a pooled and flat stepped spillway on energy losses. FLOW3D, which is computational fluid dynamics (CFD) program, with mesh size 0.015 mm used for purpose. First, code tested against an available experimental model data both water flow depth inception point position. outcome precisely shows agreement laboratory work. Second, dissipation residual head two different types spillways, pool computationally compared. results show that in spillway, larger than step. In addition, reduces chutes.
