Turbulent Characteristics and Air Entrainment Patterns in Breaking Surge Waves
Fluids, 2021 Breaking surge waves are highly turbulent three-dimensional (3D) flows, which occur when the water flow encounters a sudden change in depth or velocity.

Hydraulic Performance of Wave-Type Flow at a Sill-Controlled Stilling Basin
Applied Sciences, 2023 Downstream of the sluice gate or weir, wave-type flows inevitably occur in stilling basins with no tailwater. This paper aims to investigate the hydraulic performance of wave-type flows at a sill-controlled stilling basin through experimental research ...

Air entrainment in hydraulic engineering [PDF]
, 2004 Despite the relevance of 'white water' phenomena to hydraulic engineering, most progresses have been led by multiphase flow experts. In this paper the writer reviews the basic mechanisms of air entrainment : singular aeration and interfacial entrainment. He presents a ba-sic dimensional analysis and he discusses similitude and scale effects.

Air Entrainment and Slope Erosion During Overflow on a Levee Covered by Non-Uniform Turfgrass
FluidsTo mitigate flood damage caused by overflow from a levee, it is essential to prevent the levee failure or extend the time to breaching. Although turfgrass on a levee slope is effective in suppressing erosion, insufficient maintenance can reduce its ...

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
