The role of airflow in airborne transmission of COVID 19

Rodolfo Guzzi
In this paper the spreading of virus for air pathway has been investigated with simple examples using the Navies Stokes equations and their application with uncompressible flow and in presence of convection due to heat transfer. From the results we argue the minimum spacing for safety between persons depends on the ratio between the high and length of a manufact, here shown as a cavity box. We found the best spacing of people is obtained when the ratio is 1:5. That means the safety is to stay
