On the mechanism of air entrainment by liquid jets at a free surface

Y Zhu, HN Oğuz, A Prosperetti - Journal of Fluid Mechanics, 2000 - cambridge.org
The process by which a liquid jet falling into a liquid pool entrains air is studied
experimentally and theoretically. It is shown that, provided the nozzle from which the jet …

Mechanism of air entrainment by a disturbed liquid jet

CD Ohl, HN Oguz, A Prosperetti - Physics of Fluids, 2000 - pubs.aip.org
It was shown in recent work that the crests of surface disturbances on a falling jet are a
powerful agent for air entrainment at the free surface of a liquid pool. The paper explores the …

Numerical simulation of the accumulation process in modulated liquid jets of defined volume using the volume-of-fluid methodology

M Finster, H Chaves, R Schwarze - International Journal of Multiphase …, 2023 - Elsevier
Axial modulation of liquid jets leads to the well-known jet 'bunching'effect. The associated
accumulation of liquid in certain parts of the jet is advantageous, as it can increase the …
