Abstract

The recent Covid-19 pandemic raises unprecedented questions regarding the spread of SARSCoV-2 virus or any other contagion disease. How long viruses remain in a room? How safe am I in a crowded room equipped with a poor ventilation system? Will an open window decrease the risk of virus transmission in public places? A deeper understanding of the drop propagation laden with viruses in confined environments is essential for controlling the recent Covid-19 pandemic and preventing the next epidemic waves. For addressing above questions, a numerical simulation of cough and propagation of the respiratory droplets is performed in this paper. Effects of air conditioner and ventilation on spreading the viruses are studied and suspension time of the aerosols and their size will be provided.
In this paper study of cough flow and the spreading of the cough droplets has been investiga ted. First the capability of the flow solver is validated by comparing the velocity field with experimental data. Then the propagation of the drops is studied.
