Consistent perturbation expansion for phase-changing material in a finite domain
Peter B. Kahn, Yair Zarmi · Journal of Applied Physics · 1987
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.
