Flow Characteristics of Skimming Flows in Stepped Channels [PDF]

open access: yesJournal of Hydraulic Engineering, 2004
Ohtsu et al. must be congratulated for their systematic study of skimming flows on stepped channels with different slopes and step heights. Their experimental data provide a solid database that might lead to better and improved design criteria. Important outcomes include some estimate of friction factors for skimming flows and a design flow chart for ...

Aerated flow characteristics of skimming flow over stepped chutes

Journal of Hydraulic Research/De Recherches Hydrauliques, 2012
Stepped chutes effectively dissipate the energy of supercritical flow of steep channels. In general, stepped chute flows are characterized by self-aeration. For their hydraulic design, it is important to know the aerated flow depth, the aerated flow velocity, the air concentration, and the specific energy. Herein, quasi-uniform aerated skimming flow is

Experimental Study of Turbulence Manipulation in Stepped Spillways: Implications on Flow Resistance in Skimming Flows [PDF]

open access: yes, 2005
Current expertise in air-water turbulent flows on stepped chutes is limited to laboratory experiments at low to moderate Reynolds numbers on flat horizontal steps. In this study, highly turbulent air-water flows skimming down a large-size stepped chute were systematically investigated with a 22 degree slope.

Self-Similarity of Air-Water Flows in Skimming Flows on Stepped Spillways [PDF]

open access: yes, 2007
Skimming flows on stepped spillways are characterised by a significant rate of turbulent dissipation on the chute. Herein an advanced signal processing of traditional conductivity probe signals is developed to provide further details on the turbulent time and length scales.

Experimental investigations of air entrainment in transition and skimming flows down a stepped chute [PDF]

open access: yesCanadian Journal of Civil Engineering, 2002
Stepped spillways have been used for about 3500 years. The last few decades have seen the development of new construction materials, design techniques, and applications, for example, embankment overtopping protection systems.

Hydraulics of skimming flows on stepped chutes: The effects of inflow conditions? [PDF]

open access: yesJournal of Hydraulic Research/De Recherches Hydrauliques, 2006
Modern stepped spillways are typically designed for large discharge capacities corresponding to a skimming flow regime for which flow resistance is predominantly form drag.
