Effects of End Sill and Step Slope on Stepped Spillway Energy Dissipation
In this study, experimental procedure and laboratory works have been conducted to investigate the energy loss rate on stepped spillway, using inclined steps together with end sill. To have a more elucidated investigation inclined steps with different slopes (Horizontal , 7, 10, and 12 degrees with respect to the horizon) and end sill with different thicknesses (5 and 10 mm) and heights (6, 8, 1...
متن کاملInfluence of Slope and the Number of Steps on Energy Dissipation in Stepped Spillway Using Numerical Model
Recently the stepped spillways have been used as an appropriate solution for energy dissipation. In the present study, Siahbisheh dam spillway is simulated by using Computational Fluid Dynamic (CFD), in which the Mixture method and Reynolds Stresses Model (RSM) turbulence model is used. In the first modeling series the over all steppes slope is constant. The number of the steps is increased to ...
متن کاملEnergy Dissipation down a Stepped Spillway with Non- Uniform Step Heights
While most stepped spillway design guidelines were developed for uniform step heights, a nonuniform stepped design might be a practical alternative in some cases. A physical study was conducted in a moderate slope stepped chute (1V:2H) and five stepped configurations were tested for 0.7 < dc/h < 1.9. Detailed air-water flow measurements were performed for each configuration and the results were...

متن کاملnew approach for estimating of energy dissipation over stepped spillways
hydraulics of stepped spillway is a very complicated phenomenon, as it consists of a two phase flow passing through a set of designed steps. the steps increase the rate of energy dissipation taking place on the spillway face. turbulence, flow aeration and energy dissipation are the main tasks in the design of such structures. this study consists of the experimental investigation to determine th...
