Аннотация

This paper presents numerical simulations of pollutant transport in urban area including effects of developed turbulence, buoyancy and stratification. To  incorporate the effect of stratification in the incompressible flow solver Boussinesq approximation to the density variation was used. To properly model vertical turbulent heat and concentration fluxes Algrebraic Flux Model was used. The results presented in this paper have demonstrated that the inversion layer creates strong capping region, disallowing polluted air to mix with fresh air in the upper layer of the  atmosphere.
