title: Study on evaporation characteristics of a sessile drop of sulfur mustard on glass.
abstract: The evaporation characteristics (evaporation rates and process) of a sessile drop of sulfur mustard on glass has been studied using a laboratory-sized wind tunnel, gas chromatograph mass spectrometry, and drop shape analysis. It showed that the evaporation rates of the droplet increased with temperature and air flow. The effect of temperature on the rates was more pronounced at lower air flow. Air flow was less effective at lower temperature. The contact angle of the droplet was initially observed as θ = 19.5° ± 0.7 and decreased linearly with time until it switched to a constant mode.
