Abstract

In order to study pollutants dispersion in a stable atmospheric boundary layer, an experimental program consisting in measuring turbulence fluctuations and pollutants dispersion in a stratified surface layer and in near field is being conducted on the site ‘SIRTA’ in the southern suburb of Paris. Turbulence is characterized to be strongly anisotropic in a stable surface layer. Forest to the north of experiment field induces a strong wind directional shear between 3 m and 30 m levels and a wind speed decrease. Numerical simulation in RANS mode with k-ε turbulence closure and a canopy model enables to reproduce the observed wind channeling effect of forest on the mean flow and turbulence kinetic energy. A preliminary simulation taking into account the real pollutants flow rate has been performed and compared with measurements.
