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 ...

Measurement of the Film Thickness, Film Velocity and Entrainment Fraction in a Liquid-Air Annular Flow Using a Conductance Flowmeter [PDF]
, 2009 In certain older oil wells in the Middle East, the produced fluid is predominantly natural gas which flows at very high rates (e.g. 50,000 m3 / day ). Smaller quantities of crude oil (e.g. 50m3 / day ) and water (950m3 / day ) are also produced.
