Mixing of a stratified fluid by a decaying turbulent flow

Vertical cut of a 3D numerical simulation of a turbulent decaying flow in a initially linear stratified fluid (left), and the horizontally averaged profiles (right). The velocity field generates irreversible mixing in a stratified fluid. The horizontally averaged vertical profile evolves in time, nevertheless, the instantaneously irreversible mixing can only be observed by sorting the buoyancy field in the whole volume.
