Recent trends in stepped spillway design: behaviour without sidewalls

Until now, hydraulic research of stepped spillways has focused on characterizing aspects as: the different types of flow that occur on the dam, the air inception processes, the potential negative effects associated to the risk of cavitation, the energy ...

Numerical investigation of alternating skimming flow over a stepped spillway

Water Science and Technology: Water Supply, 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 ...

Stepped Spillway Slope Effect on Air Entrainment and Inception Point Location

Water (Switzerland), 2021
Spillway is a crucial hydraulic structure used to discharge excess water from the dam reservoir. Air entrainment is essential to prevent cavitation damage on the spillway, however, without air entrainment the risk of cavitation over the spillway ...
