TL;DR: In this paper, the influence of vortical structures on a two-density fluid indicate a possible motion of the light fluid into the heavy one and vice versa, and the results provide an insight into the fast burning observed along vortex tubes.

TL;DR: In this paper, the effects of stablity on the downstream growth and mixing of the turbulent boundary layer, and the changes in velocity and concentration profiles were examined, and a finite difference/volume code with no subgrid scale model was used for the simulations.
Abstract: Direct numerical simulations (DNS) have been undertaken of a smooth-walled, low Reynolds number turbulent boundary layer (R θ ≈ 800) over a flat plate, with injection of fluid through a slot in the upstream end of the plate. The injection of a mixture of ambient and dense gas served to trip the boundary layer as well as providing the stable density stratification. Bulk Richardson numbers varied from zero (neutral) to 0.035 (stable). A finite difference/volume code with no subgrid scale model was used for the simulations, and the number of grid cells employed (255 × 96 × 96) was found to be adequate to resolve most of the turbulent motions. Examined here are the effects of stablity on the downstream growth and mixing of the turbulent boundary layer, and the changes in velocity and concentration profiles.
