Abstract
We have measured the sublimation rate of trace quantities of explosives materials as a function of temperature, airflow, inter particle distance, and humidity. In parallel, we have developed a computational model based on Monte Carlo simulation and molecular dynamics to predict sublimation behavior. Together these allow us to predict the persistence of arbitrary particle ensembles provided that certain physical properties such as vapor pressure are known. This data can be used to inform those developing vapor or particle based sensing technologies.
