Mixing in stably stratified turbulent flows : improved parameterizations of diapycnal mixing in oceanic flows
Mixing of fluid with different properties across a gravitationally stable density interface, due to background turbulence is an ubiquitous phenomenon in both natural and engineered flows. Fundamental understanding and quantitative prediction of turbulent mixing in stratified flows is a challenging problem, with a broad range of applications including (but not limited to) prediction of climate, ocean thermohaline circulation, global heat and mass budget, pollutant and nutrients transport, etc. Large scale geophysical flows such as in the ocean and atmosphere are usually stably stratified i.e. the ...
