EULERIAN AND LAGRANGIAN STATISTICS IN HOMOGENEOUS STRATIFIED FLOWS

The present work follows previous modelling efforts of homogeneous str atified turbulence, using a statistical Eulerian model, with a high le vel of description of anisotropy, and a kinematic simulation model for computing Lagrangian dispersion properties of turbulence. Here, both approaches are coupled, yielding results for the dispersion of a singl e passive particle. The first results obtained by our model qualitativ ely agree well with the one-particle dispersion ones obtained from Lar ge Eddy Simulations of stationary stratified turbulence.
