Abstract
Recently, terrorism is one of most daunted dangers in the world. Chemical terrors have high mortality rate, and tend to wreak the secondary disaster. For these reasons, research and development of measures for decontaminations are emergent. Chemical agents emission and infiltration are usually investigated with experiments, but the experiment is so dangerous because of the toxicity. Therefore, in this study, computational fluid dynamics is used to reproduce evaporation and infiltration of chemical agents. Comparing the numerical results with the experimental data, it is confirmed that the numerical data are in good agreement with the experimental data. In addition, volatilization volume and infiltration volume are coupled with droplet geometry to simulate the temporal change of droplet shape and residual mass.
