Abstract
A general analytical solution for the steady-state evaporation from deformed liquid drops is proposed. The solution is applicable to classes of drop shapes for which 1-D solution exists. The method is used to find the evaporation rate and local vapour and heat fluxes for general ellipsoidal drops, extending previous available results on spheroids. A direct dependence of the local vapour flux on the surface Gaussian curvature is evidenced. A quantitative evaluation of the effect of drop deformation on the total evaporation rate and the local vapour flux is reported.File | Dimensione del file | Formato | |
