Understanding how turbulence leads to the enhanced irreversible transport of heat and
other scalars such as salt and pollutants in density-stratified fluids is a fundamental and …

The offshore wind energy sector has rapidly expanded over the past two decades, providing
a renewable energy solution for coastal nations. Sector development has been led in …

Direct numerical simulations of stably and strongly stratified turbulent flows with Reynolds
number Re≫ 1 and horizontal Froude number Fh≪ 1 are presented. The results are …

It is well-known that strongly stratified flows are organized into a layered pancake structure
in which motions are mostly horizontal but highly variable in the vertical direction. However …

This paper shows that a long vertical columnar vortex pair created by a double flap
apparatus in a strongly stratified fluid is subjected to an instability distinct from the Crow and …

We present laboratory experiments on turbulence in a linearly stratified fluid driven by an
ensemble of internal gravity waves which approaches statistical homogeneity and …

The mean velocity profile scaling and the vorticity structure of a stably stratified, initially
turbulent wake of a towed sphere are studied numerically using a high-accuracy spectral …

Numerical simulations of forced stratified turbulence are presented, and the dependence on
horizontal resolution and grid aspect ratio is investigated. Simulations are designed to …

We study direct numerical simulations of turbulence arising from the interaction of an initial
background shear, a linear background stratification and an external body force. In each …

We study the morphology of Eulerian vortical structures and their interaction with density
interfaces in increasingly turbulent stably stratified shear layers. We analyse the three …
