Abstract

In a previous paper in the framework of the extended irreversible thermodynamics with internal variables a non conventional thermodynamical model for fluid flow through porous solids was given introducing in the state space a second order structural permeability tensor à la Kubik (describing a network of thin porous channels in an elastic body filled by fluid flow) and its flux as internal variables. Here, using a geometrization technique for the thermodynamics of simple continua we derive the entropy function and, exploiting the Clausius-Duhem inequality by Maugin technique, we obtain the laws of state and the heat equation.
