dc.description.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. |
