Computer simulations of evaporation of pinned sessile droplets: Influence of kinetic effects
journal contributionposted on 2017-07-17, 12:19 authored by Sergey Semenov, Victor Starov, Ramon Rubio, M.G. Velarde
The aim of the current work is to present results of computer simulations, which show the influence of kinetic effects on evaporation of pinned sessile water droplets of submicrometer size placed on a heat conductive substrate. The computer simulation model also takes into account the following phenomena: influence of curvature of the droplet’s surface on saturated vapor pressure above the surface (Kelvin’s equation), the effect of latent heat of vaporization, thermal Marangoni convection, and Stefan flow inside an air domain above the droplet. The suggested model combines both diffusive and kinetic models of evaporation. The obtained results allow the characteristic droplet sizes to be estimated, where each of the mentioned above phenomena becomes important or can be neglected
