Analysis of Numerical Simulations of Stratified Turbulence
Abstract
The objectives of the proposed research are: to better understand the nonlinear dynamics of turbulent, strongly stratified flows, and to test various existing subgrid-scale models for use in large-eddy simulations of turbulent, strongly stratified flows, possibly suggesting new modeling. The approach is to further analyze data from existing high-resolution direct numerical simulations, both for cases of decaying, homogeneous flows and of forced, stationary flows. If successful, a better understanding of the nonlinear dynamics will be obtained and, in particular, of spectral energy transfer. This understanding of spectral energy transfer will help in evaluating subgrid-scale modeling, leading to testing of existing modeling and possibly suggesting new models.
