The dynamics of airflow in narrow corridors increases the risk of coronavirus infection. The study was published in the journal Physics of Fluids by American scientists. Using simulations, researchers at the American Institute of Physics have studied how the surrounding space affects the spread of virus particles during walking.
First, they determined the airflow patterns, and then they created a program that predicted the dissolution of a cloud of droplets from a person's mouth when he sneezed or coughed. Scientists have found two dispersion regimes. In the first, the drop cloud, which is characteristic of open areas and is formed, remains around the person and gradually dissipates. In the second, the cloud, which is characteristic of narrow corridors, separates from the moving person and forms a foam, leaving it far behind. Experts have concluded that the risk of infection is higher in the second case.
