Bubble-turbulence interactions model in a stochastic-LES framework

Abstract

This paper presents a novel stochastic-LES hybrid model for favre averaged bubble-turbulence interactions in free-surface flows. The current model is found to be capable of computing local behaviors of dense bubble flows coupled with fluid turbulent motion, which is ensured by comparisons with experimental observations. The model is also applied to the flow at a planar jet impact onto a still water, as a model of overturning jets of breaking waves, which reasonably computed cavity deformation, air tube entrainment and bubble formations.
