Modeling of Atmospheric Dispersion of Pollutants Through the Building using a Lagrangian Stochastic Model

In this paper, we will present a summary of recent studies made to model the atmospheric dispersion around a building using Computational Fluid Dynamics (CFD). So we will focus on the studies made by Bahlali et al, who uses the Lagrangian stochastic CFD model implemented in Code_Saturne to model our problem taking into account atmospheric stratification. Our work essentially consists in showing the importance of this model by commenting on the results of the work obtained by Bahlali et al.
