Abstract
This project is a study of how a sessile drop evaporates on a hot surface. Some
existing models of droplet evaporation are explained, understood, simulated and compared.
This project also provides an expression of drop interface velocity according to
contact angle evolution. Considering pinned contact line, the droplet as a spherical
cap, constant mass transfer rate and neglecting gravity; the models are computed
using COMSOL Multiphysics and Matlab. A part from smooth surfaces, the droplet
evaporation models are used also in rough surfaces. There is good agreement with
experimental data on smooth and rough surfaces. The best studied model gives a
relative error of 9% in relation to experimental data.
