MATHEMATICAL MODELS FOR EVAPORATION OF THIN FILMS

model was derived using a thin film approximation which related film thickness, evaporation rate and fluid motion. Further, expression for evaporation rate was developed for the deformed thin film where vapor diffusion outside the film limited the evaporation of liquid molecules. We hope to adapt this model of thin film
