| Outline of Final Research Achievements |
To prevent the damage in outbreak of high virulence influenza, on droplet nuclei infection as main route of the infection, finding its mechanism and prevention were studied. It was investigated from the point of view of fluid dynamics. Using airflow computation with parameters of virus and its environment based on virology, behaviour of influenza virus was calculated in a high accuracy. In the case of computation for flows in an indoor environment, unstructured mesh system was adopted to express a detail shape of human. Then, delicate flow changes with sneezing and coughing were computed using active boundary conditions. In the case of flows in respiratory tract, a motion of breathe with lungs were expressed using the moving grid method to specify viral landing points. Furthermore, we tried to develope the fluid dynamics engineering vaccine to prevent the infection by controlling an airflow. Also, a consecutive calculation among indoor and respiratory tract is nearly completed.
