Sinopsis

Substances which during melting or solidification undergo further changes of phase in the solid produce or absorb an additional amount of latent heat. These secondary transformations may occur either continuously within a certain temperature range or at certain fixed temperatures. Calculations were performed for the one-dimensional case by an implicit finite difference method. All changes of thermal conductivity, specific heat and density, continuously with temperature as well as abruptly at phase interfaces were included. Following a general discussion of the influence of the governing parameters the example of solidifying iron and the case of salt solutions solidifying with liquid enclosures are specifically treated.
