Abstract:

An original model of turbulent pollutant transport is presented. Algebraic expressions for turbulent mass flows , , in the form of simple gradient closure relations are derived within this model on the assumption of near-equilibrium turbulence. The model is tested with fundamental experimental data for various conditions of atmospheric stratification, dynamics of the atmospheric boundary layer, and turbulent dissipation of a pollutant from a surface source. The obtained relationships for turbulent mass flows are used in the model of pollutant transport taking into account the chemical transformations of transported substances in order to study the formation and dissipation of secondary pollutants in the air layer over a city and its suburbs.
