Evaluating the critical velocity of air entrainment by plunging water jets [PDF]

open access: yesE3S Web of Conferences, 2023
It has been found that air entrainment occurs when the average jet velocity at the plunging point reaches a certain value. This velocity is called the critical velocity of air entrainment.

Influences of an entrainment–mixing parameterization on numerical simulations of cumulus and stratocumulus clouds [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Different entrainment–mixing processes can occur in clouds; however, a homogeneous mixing mechanism is often implicitly assumed in most commonly used microphysics schemes.
