Asymptotic analysis of mixing in stratified turbulent flows, and the conditions for an inertial sub-range

Andrew D. Bragg, Stephen M. de Bruyn Kops

In an important study, Maffioli et al. (J. Fluid Mech., Vol. 794 , 2016) used a scaling analysis to predict that in the weakly stratified flow regime $F{r}_h\gg 1$ ($F{r}_h$ is the hori…
