抄録

Recently, various terrorisms come about and threaten people in the world. Because of the high fatality rate, biological and chemical weapons are recognized as the most dangerous weapons in all other ways of terror. For these reasons, research and development of measures for decontaminations are emergent and key issues on a world scale. However, the experiments are highly risky and legally prohibited in many cases. Therefore, computational fluid dynamics (CFD) is useful to research and develop the decontamination methods. In order to simulate decontaminations, it is necessary to know chemical agent (CA) behaviors. In the present study, we propose the three-dimensional volatilization model which can estimate the volatilization from a contaminated substrate by using CFD. The model predictions give good agreements with the experimental data.
