Structure of Turbulence and Subgrid-Scale Modeling.

Abstract

Transformation from homogeneous to nonhomogeneous turbulent flows is developed, based on some properties of the Navier-Stokes equations. This transformation is successfully applied to the turbulent wake, produced by a model-scale frigate. Some new schemes for the large-eddy simulations of turbulent flows are developed, tested by direct numerical simulations and compared with experiments.
