The objects of this study are to observe the detailed distribution of air velocity and CO_2 (carbon dioxide) concentration which is used as tracer gas of coughed air and to calculate advance conditions concerning droplet dispersion counting on relative humidity and pressure. The full scale chamber where the experiment was conducted was modeled and then the experimental conditions were input. The elaborative mock was achieved. The results of CFD illustrated the high CO_2 concentration area and many tiny droplets were observed near the medical doctor. Hence the infection risk was still high when the medical doctor moves.
