SEMENOV, S. ...et al., 2011. Evaporation of sessile water droplets: Universal behaviour in presence of contact angle hysteresis. Colloids and Surfaces A: Physicochemical and Engineering Aspects, 391(1-3), pp. 135-144.
A theory is presented, which describes the diffusion limited evaporation of sessile water droplets in presence of contact angle hysteresis. Theory describes two stages of evaporation process: (I) evaporation with a constant radius of the droplet base; and (II) evaporation with a constant contact angle. During stage (I) the contact angles decreases from static advancing contact angle to static receding contact angle. During stage (II) the contact angle remains equal to the static receding contact angle. Universal
dependences are deduced for both evaporation stages. Obtained universal curves are validated against available in the literature experimental data.
