Abstract
The stratified backward-facing step flow is a useful prototype configuration both in geophysical fluid dynamics (flow behind mountains for instance) and in nuclear engineering (heat exchangers in fast breader reactors). The purpose of this paper is to use large-eddy simulations in order to characterize the dynamics of coherent structures shed behind the step. It will be done first in the non-stratified case. Then we will look at the effect of a stable stratification brought into the incoming flow.
