The Lifetimes of Evaporating Sessile Droplets of Water Can Be Strongly Influenced by Thermal Effects

The effect of the thermal properties system on lifetime an evaporating sessile droplet water is analysed using a fully coupled model which involves determining temperature droplet, substrate and atmosphere. evolutions, hence lifetimes, droplets in both extreme modes are calculated. In particular, it shown how lifetimes can be strongly influenced by effects. Droplets with larger initial contact angles or less conductive substrates generally have longer than those smaller more substrates, physical mechanism influence evaporation understood terms anchoring between lower surface substrate.
