Two-point closures and turbulence modeling

Résumé

The main ideas underlying the derivation of the usual two-point closures are reviewed. The Direct Interaction Approximation (DIA) and related closures, and the Eddy-Damped Quasi Normal Markovian (EDQNM) model are briefly presented. Particular emphasis is given to the application of closures to homogeneous anisotropic turbulence. The relations between two-point closures and other types of turbulence models, in particular subgrid models for Large-Eddy Simulations, are briefly presented. Finally, the possible extensions of two-point models to inhomogeneous turbulence are discussed and some representative results are given.
