Abstract

A numerical study of the transport and dispersion of heavy particles in the atmospheric boundary layer is carried out by an Eulerian-Lagrangian approach, in which the carrier flow is simulated by an Eulerian code and the dispersed phase is simulated by tracking simultaneously the random Lagrangian particle trajectories, solving their complete equation of motion, and the fluid eddies interacting with them. The model predictions are compared with recent experimental data obtained by Taniere et al. [1] in the turbulent boundary layer of a wind tunnel flow. 1. Introduction Usually Lagrangian model
