Abstract

The analysis and solution to a variation of the classical Stefan-Neumann problem of melting and solidification in a porous medium is presented in this paper. The specific novel aspect in this paper is the subjecting of the top boundary to periodic freezing and melting conditions and the application of the latter to water saturated asphalt. The results show as anticipated by the analysis a sequence of chasing fronts from the surface to the interior.
