Analysis of melting in the presence of natural convection in the melt region
TL;DR: In this article, an analysis of multidimensional melting is performed which takes account of natural convection induced by temperature differences in the liquid melt, and the results differ decisively from those corresponding to a conventional pure-conduction model of the melting problem.
