Study of airflow and pollutant transport in an urban street canyon using large eddy simulation of the turbulent flow

In this paper, the large eddy simulation model is presented, as well as a modification of the algortihm for numerical solving the system of Navier–Stokes equations. The modification is oriented to the supercomputer technique. After approbation of the constructed model on test problems, the proposed mathematical model was applied to studying the airflow and pollutant transport in an urban street canyon.
