Mechanism generating reverse buoyancy flux at the small scales of stably stratified turbulence
Soumak Bhattacharjee, Stephen M. de Bruyn Kops, Andrew D. Bragg
Previous studies have shown that at the small-scales of stably stratified turbulence, the scale-dependent buoyancy flux reverses sign, such that there is a conversion of turbulent…

Area of Scalar Isosurfaces in Homogeneous Isotropic Turbulence as a Function of Reynolds and Schmidt Numbers
Kedar Prashant Shete, Stephen M. de Bruyn Kops
A fundamental effect of fluid turbulence is turbulent mixing, which results in the stretching and wrinkling of scalar isosurfaces. Thus, the area of isosurfaces is of interest in u…
