چکیده مقاله
Computational modeling of pollutant transport, dispersion and deposition is described Particular attention is given to transport and deposition of contaminant particles in atmospheric flows around buildings, in street canyons and near bridges The Eulerian Eulerian and Eulerian Lagrangian models are outlined Particular attention was given to the use of advanced anisotropic turbulence models and a Lagrangian particle trajectory analysis The procedure for simulating the instantaneous turbulence fluctuating velocity vector with the aid of random field model sis described Examples of dispersion and deposition of pollutants near buildings, in street canyons and near bridges are discussed It is shown that the computer simulation can predict the features of the experimentally observed pollutant concentration data
