Abstract
For various types of viral infectious diseases represented by influenza, it is an important issue to prevent a risk of viral infection. In addition virus can penetrate in respiratory, then viral adhesion part is difficult to revealing. In this paper, to specify where virus adhere in respiratory tract, viral movement were simulated by CFD using some parameters based on epidemiology. As the parameters, change in droplet radius because of evaporation, a sedimentation rate of particle was adopted. In addition, flows caused by breathing were also thought for the computation. As a result, visualization of viral movement was observed by the simulation. Then a possibility of contribution to specifying infection part was shown.
