Numerical investigation of alternating skimming flow over a stepped spillway
Water supply : the review journal of the International Water Supply Association, 2021 This study aims to illustrate the influence of stepped spillway width on alternating skimming flow development. A computational fluid dynamics (CFD) model in Ansys Fluent® was established to simulate the flow over stepped spillways, using a volume of ...

Experimental study of skimming flow on the stepped spillway in the non-aerated area using PIV [PDF]
هیدرولیکUnderstanding the flow behavior over stepped spillways has been the subject of many previous studies. Most of the studies conducted on stepped spillways have been in skimming flow conditions and the aerated parts of the spillway.

Multi-objective optimization of stepped spillway and stilling basin dimensions
Water supply : the review journal of the International Water Supply Association, 2021 In the present paper, an optimization procedure is proposed for stepped spillway design dimensions, which leads to maximum energy dissipation rate and minimum construction cost, considering independently the chute cost and stilling basin cost.

Stepped Spillway as an Energy Dissipater [PDF]
Canadian Water Resources Journal / Revue canadienne des ressources hydriques, 2004 This paper describes an experimental investigation into the hydraulics of ogee-profile stepped spillways, examines their viability as an alternative to smooth-back spillways and investigates their efficiency in reducing the downstream energy and length of the hydraulic jump.

Predicting the Flow Velocity at the Toe of a Labyrinth Stepped Spillway
The Journal of Engineering Research [TJER], 2021 The velocity at the toe of a spillway is a major variable when designing a stilling basin. Reducing this velocity leads to reduce the size of the basin as well as the required appurtenances which needs for dissipating the surplus kinetic energy of the ...

Alexandria Engineering Journal, 2021 To protect the dam body and downstream area, spillways should be built. Because the difference in water level upstream and downstream spillways is usually very big, energy dissipation facilities should be introduced.
