On the use of CFD for modelling air pollutant dispersion around buildings

Abstract

CFD is increasingly used to address a wide range of topics in Wind Engineering. This paper provides an overview of the use of CFD for modelling wind-induced dispersion of air pollutants around buildings. The focus is on dispersion around an isolated building, as the generic basic case for dispersion in the urban environment. RANS and LES modelling are briefly described, and the advantages and disadvantages of both techniques are discussed. CFD studies of dispersion around isolated buildings are reviewed along with past achievements and future challenges. In spite of considerable progress made in the past, it is concluded that many challenges still need to be overcome before CFD can become a stand-alone tool in pollutant dispersion modelling.
