Abstract
The COVID-19 pandemic raised the importance of breathing clean air in public establishments. High con- tamination of airborne diseases are expected during the winter, but recent studies does not indicate simple results. Some authors have approached the problem using Computational Fluid Dynamics (CFD) to simulate various scenarios to inves- tigate different factors regarding the main cause of airborne disease transmission. However there is still not a consensus on how exactly is the mechanism of transmission. In this context, the present work uses CDF via software OpenFOAM to simulate the airflow and saliva particle dispersion on an event of a human cough. The model considers an Eulerian- Lagrangian method is used to track individual droplets of saliva in the airflow in a two-dimensional domain.
