Thermodynamics for Fluid Flow in Porous Structures

Maria Elena Malaspina, Liliana Restuccia

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.
