Solution of the Atmospheric Diffusion Equation with Longitudinal Wind Speed Depending on Source Distance

Solution of the Atmospheric Diffusion Equation with Longitudinal Wind Speed Depending on Source Distance

Abstract An integral semi-analytical solution of the atmospheric diffusion equation considering wind speed as a function of both downwind distance from a pollution source and vertical height is presented. The model accounts for transformation and removal mechanisms via both chemical reaction and dry...
