Melting and dissolving
Abstract
The different modes of convection which may arise in diffusiongoverned melting of a pure solid into a binary melt, when the interface between the solid and the melt is horizontal are investigated. It is shown that, in the dissolving regime, a relatively warm solid may dissolve into a relatively cold liquid. The nature of the convection which may arise as the geometry and the melt composition are varied is determined by calculating the difference between the density of the melt at the solid interface and the density of the liquid far from the interface. The analysis is generalized by considering binary solid solutions.
