On entrainment at stratified interfaces
Abstract
A study is reported of the behavior of a stratified interface, taking into account influences from other dimensionless quantities in addition to the Richardson number. A mechanism is noted for producing intermittent entrainment when an interface separates a relatively dense turbulent fluid from a nonturbulent lighter fluid at a higher virtual temperature. The dependence of the entrainment velocity on the dynamic parameters is examined. Among the related works cited are Turner (1968) and Deardorff et al. (1969).
