Modeling and simulation of the potential indoor airborne transmission of SARS-CoV-2 virus through respiratory droplets

Respiratory viruses are transported from an infected person to other neighboring people through respiratory droplets. These small droplets easily advected by air currents in a room and can potentially infect others. In this work, the spread of released during coughing, talking, normal breathing is numerically analyzed typical conference setting. The space occupied ten people, with eight sitting around table two standing. Four different scenarios considered, air-conditioning turned on/off wearing/not-wearing masks, understand inside room. flow simulated using multiphase mixture model properties computed for inhaled exhaled fundamental gas relations. transport discrete phase range droplet sizes fitted data previous experimental studies. mask modeled as porous media woven fabric newly developed multilayered homemade masks. human inhalation exhalation analytical functions mimic biological patterns breathing, talking. Important observations about dispersion presented based on numerical analysis. Animations all results included provide insight into physics various dynamic conditions occurring ongoing meeting. Although study conducted room, models techniques be applied confined environments.
