摘要

Usually, the Stefan problem is associated to the crystallization of melted solids, in which the energy transfer (heat diffusion) dominates the process. In the present work, the Stefan problem was solved for the crystallization of solutions, i.e., a situation in which mass transfer is the most important phenomenon. An analytical solution was obtained for the equation describing the the crystallization of a binary or pseudo-binary system. From this solution, a mathematical expression for the crystal growth was obtained as a function of time, degree of supersaturation, liquid diffusivity and solution mole concentration. It was observed that the expression for the crystal growth agrees qualitatively well with experimental data reported in the open literature.
