Sharp interface limit of a homogenized phase field model for phase transitions in porous media

Martin Hopker

Abstract:
A homogenized phase field model for phase transitions in porous media is considered. By making use of the method of formal asymptotic expansion with respect to the interface thickness, a sharp interface limit problem is derived. This limit problem turns out to be similar to the classical Stefan problem with surface tension and kinetic undercooling.
