Implicit enthalpy formulation of phase-change problems on unstructured grid

This paper presents an implicit finite-volume enthalpy formulation of the multidimensional phase-change problems involving a unique phase-change temperature. The derived formulation provides a simple method for local tracking of interface using the enthalpy variable on both structured as well as unstructured grids in a novel way. Results of economic computations of previously published problems are presented. Copyright © 2003 John Wiley & Sons, Ltd.
