A series of experiments on the flash evaporation−freezing process of pure water droplets released into vacuum have been performed in order to reveal the influences of randomicity, with particular attention being paid to the random characteristics of the relevant sub-processes. It was clearly observed that the nucleation time is a random, independent variable that drastically affects the nucleation temperature and supercooling. Both the nucleation temperature and supercooling are not dependent on the terminal environmental pressure. They exhibit similar means and standard deviations at different terminal environmental pressures. The freezing time is independent of the nucleation time, but exhibits an obvious dependence on the terminal environmental pressure and drop diameter. The freezing temperature exhibits a much more complicated characteristic, which may be determined by the real atmosphere around the droplets. The measured quantitative characteristics will be helpful in developing a model to predict the flash evaporation−freezing process of pure water droplets during quick depressurization.
