Resumen:
Formulas are obtained for the simultaneous determination of two or three unknown thermal coefficients of a semi-infinite material with temperature-dependent thermal conductivity through a phase-change process with an overspecified condition on the fixed face through a moving boundary problem (inverse Stefan problem) or a free boundary problem (Stefan problem) respectively. We complete and improve the analysis done in Tarzia, Int. Comm. Heat and Mass Transfer, 25 (1998), 139-147 and we also study the sensitivity of the solution depending on different thermal parameters, applied to aluminum.
