Similarity solutions for thawing processes with a heat flux condition at the fixed boundary

Similarity solutions for a mathematical model for thawing in a saturated semi-infinite porous medium is considered when change of phase induces a density jump and a heat flux condition of the type -q0t-(1/2) is imposed on the fixed face x = 0. Different cases depending on physical parameters are ana...
