Numerical modeling of turbulent transport of impurities in a spatially inhomogeneous atmospheric environment

This study presents a mathematical model for turbulent pollutant dispersion in urban airflows based on the Navier-Stokes equations and the ????−???? turbulence model. The model incorporates meteorological parameters, emission sources, and urban structures. A finite difference numerical method is used to solve the equations. Computational experiments demonstrate pollutant concentration patterns in urban environments. The results indicate that wind turbulence and building geometry significantly influence dispersion. The model can aid in urban planning and environmental safety. Simulation findings highlight the importance of wind circulation in reducing pollution. The study provides practical recommendations for optimizing urban design.
