The most difficult way to prevent infection among some infection routes is viral droplet nuclei transmission. Droplet nuclei are generated during coughing and sneezing, and suspend for a long time. Hence, specifying its infection route is important issue. The behavior of the droplets is governed by the physical principles. In addition, environmental factors, such as temperature, relative humidity and droplet size, also affect their dispersion and determining the survival. Thus, in this paper, first airflow in the crowded train was analyzed by using CFD.
