Numerical simulations of aerosol motion induced by sneezing and exhalation were carried out by CFD (Computational Fluid Dynamics) with modeled particles. For sneezing analysis, with and without covering by an elbow and wearing a face mask were modeled to clarify the effect of how to prevent scattering. Aerosol scattering from a talking passenger in a ventilated train was also analyzed to show a realistic situation that may cause infections of the virus. Those results have been published on the web through several SNSs to promote understanding the effect of infection prevention manner.
