Étude numérique de la dispersion des particules lourdes dans une couche limite turbulente

Abstract

The aim of this paper is to present modifications brought to a standard Lagrangian model for turbulent dispersion so that the forces acting on a heavy particle in a turbulent boundary layer can be taken into account. A satisfying validation of this modified model for Lagrangian trajectography is then obtained and compared with the experimental results of Tanière et al. performed in the boundary layer of a wind tunnel.
