A filtering approach for analyzing turbulent stratified shear flows
Stably stratified shear layers are present in many geophysical contexts from oceanic overflows to river estuaries and have been studied in many contexts in both laboratory experiments and numerical simulations. We consider here laboratory experiments on a gravity current where the current itself is turbulent [1] with a Reynolds number of a few thousand (Taylor Reynolds number of about 100) wher...
متن کامل2DV Nonlinear k-ε Turbulence Modeling of Stratified Flows
The commonly used linear k-ε turbulence model is shown to be incapable of accurate prediction of turbulent flows, where non-isotropy is dominant. Two examples of non-isotropic flows, which have a wide range of applications in marine waters, are saline water flow and the stratified flows due to temperature gradients. These relate to stratification and consequently, variation of density through...
متن کاملA Non-Fickian Mixing Model for Stratified Turbulent Flows
The long term goal of this project is to develop a better understanding of oceanic processes in the range of 100 m to 10 km, in the so-called submesoscale range. In particular, it is important to explore and find out whether and what type of submesoscale instabilities exist, how they are connected to both larger scale and smaller scale motions, and to what extent they influence transport proces...
متن کاملTurbulent mixing of stratified flows
A mathematical model for turbulent mixing of stratified, sheared flows is developed and explored. Two applications are emphasized, one to the dynamics of the ocean well–mixed layer, and another to the analysis of the stability of equilibrium profiles away from boundaries.
متن کاملTurbulent mixing in strongly stratified shear flows
Motivated by the importance of irreversible mixing in geophysical and environmental flows, we seek to understand the dependence of its efficiency under strongly stratified conditions through a seris of direct numerical simulation of Holmboe wave instability under various initial conditions. Our numerical findings demonstrate that while mixing is enhanced when the density layer is much sharper t...
