Calculations of Wind Mass Transfer of Pollution: Simulation and Analytical Models

The main goal of the present study is to compare the results of calculations of the dust mass transfer with wind using the analytical and simulation models. Analytical model is based on unsteady turbulent diffusion equation. Simulation model is taking into account four main processes of mass transfer in atmosphere: emission of pollutants, wind mass transfer, deposition and turbulent diffusion of pollutants. Calculations of pollution field from linear source were compared. It was found that both results are in good agreement. Some special features of the simulation model make it more preferable for pollution forecast calculations for the purposes of optimal environmental management.
