Recently, terrorism with chemical weapons is one of most daunted danger in the world. Chemical terror have particularly high mortality rate. VX gas is one of chemical agent used to commit terrorism. VX gas has severe toxicity and long-period damage because of persistent agent. In the present study, VX gas emission from a contaminated object surface is researched. VX gas emission is unusually analyzed with experiments, since the experiment is so dangerous because of the toxicity. Therefore, in this study, computational fluid dynamics is used to analyze the emission. We propose a volatilization model which estimates the volatilization quantity of a chemical agent with the saturated steam pressure of chemical agent and physical quantities of the air. Since the volatility characteristics of VX gas resembles that of glycerin, the model is applied and verified to glycerin volatility tests. The numerical results are compared with the experimental data.
