Formulation of a hyperbolic Stefan problem
Technical Report

OSTI ID:6462852
The study of phase change processes governed by hyperbolic heat transfer is at an embryonic stage. We raise here some of the relevant questions and make some remarks on the formulation and qualitative behavior of a hyperbolic Stefan problem. In particular, we correct an error in the interface condition appearing in the literature, present an explicit solution to a simple one-phase problem and study its behavior. Finally we describe an enthalpy (weak) formulation for a two-phase problem and report on a number of numerical experiments based on it.
