摘要
In this paper, an analytical method previously proposed for one-phase and two-phases transient mass/heat diffusion with reaction is now applied to derive closed-form solutions for the inward transient solidification of cylinders and spheres, considering a global metal/mold heat transfer coefficient. Furthermore, temperature profiles are derived for mold, solid, and liquid phases. The analytical model developed proved to be general, thus permitting to derive closed-form exact analytical solutions for pure metals and eutectics.
