Evaporation Rates of Chemical Warfare Agents Using 5 cm Wind Tunnels, IV. VX From Glass

Abstract

The evaporation of VX from glass was studied as a function of temperature, drop size, and air flow rate, using the same instrumentation as prior studies of sulfur mustard evaporation from glass, concrete, and sand. The evaporation rate increased with higher temperature and drop size; wind speed was not a significant factor. An empirical equation was determined that would allow for the calculation of the evaporation rate given the atmospheric conditions. The data collected provide input for the validation of empirical and physics-based models on the evaporation of agent designed by other authors, and are input for the VLSTRACK model, which predicts agent vapor concentrations as a function of environmental conditions.
