A Non-Fickian Mixing Model for Stratified Turbulent Flows
نویسنده
چکیده
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 processes in the ocean. Another important objective of this project is to test how well subgrid-scale (SGS) models for large eddy simulations (LES) work in the presence of backward energy cascade that may be characteristic in submesoscale motions. A long term objective of this effort would be to improve the predictive skill of the Navy numerical models for submesoscale transport in the ocean.

Flows of natural hydro-environments are usually turbulent and mostly stratified, like the flows in lakes, reservoirs, estuaries and atmosphere to name a few. In stratified flows due to the buoyancy forces, the turbulent stresses are usually non-isotropic. Therefore the accuracy of the numerical simulations for such flows is highly dependent on the turbulence model and the implementation of non-...
متن کاملModeling mixing in two-dimensional turbulence and stratified fluids
A phenomenological model for turbulent mixing in a stratified fluid is presented. This model describes the evolution of the local probability distribution for the fluid density. It is based on an analogy between the mixing of vorticity in 2D turbulent flows and the mixing of density in (3D) turbulent flows.
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 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 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...
