Consistent perturbation expansion for phase-changing material in a finite domain

A self-consistent perturbation expansion is developed for the case of a finite slab of phase-changing material with constant boundary conditions corresponding to a ‘‘two-phase’’ problem. Consistency is achieved by a power-series expansion in functions of both solid and liquid Stefan numbers. Terms t...

Zusammenfassung:A self-consistent perturbation expansion is developed for the case of a finite slab of phase-changing material with constant boundary conditions corresponding to a ‘‘two-phase’’ problem. Consistency is achieved by a power-series expansion in functions of both solid and liquid Stefan numbers. Terms through third order are calculated.
