Abstrakt
In this research, Harper’s previous experiment data on survival ratio of the influenza virus was re-analyzed from a viewpoint of absolute humidity according to Shaman. Consequently, it was confirmed that the survival ratio of the influenza virus was more correlated with absolute humidity than relative humidity. Moreover, survival change model using the half lifetime of an influenza virus based on Harper’s data was found to explain experiment results very well. The virus survival model and diffusion of a virus as a Lagrangian model was incorporated to CFD, and the case study which changed the air-conditioning system was carried out. Consequently, a possibility that indoor influenza infection would be controllable was shown by combining humidification and ventilation.Referanser
