We study a variational formulation for a Stefan problem in two adjoining bodies, when the heat conductivity of one of them becomes infinitely large. We study the `concentrated capacity' model arising in the limit, and we justify it by an asymptotic analysis, which is developed in the general framework of abstract evolution equations of monotone type.

Abstract
We study a variational formulation for a Stefan problem in two adjoining bodies, when the heat conductivity of one of them becomes infinitely large. We study the `concentrated capacity' model arising in the limit, and we justify it by an asymptotic analysis, which is developed in the general framework of abstract evolution equations of monotone type.File in questo prodotto:
