Type of article: Article

Summary

THE CONSTRUCTION OF MODELS OF NONSATURATED POROUS MEDIA IS APPROACHED USING THE THERMODYNAMICS OF IRREVERSIBLE PROCESSES. THE SOURCE OF ENTROPY IS OBTAINED BY WRITING THE GIBBS EQUATION OF EACH OF THE THREE PHASES. THE RELATIONS OBTAINED ARE IN CONFORMITY WITH KNOWN EXPERIMENTAL LAWS. THE APPROACH PROPOSED ENABLES ACCOUNT TO BE TAKEN OF PHENOMENA OCCURRING AT THE INTERFACES, SUCH AS CHANGES OF PHASE AND TRANSFER OF HEAT BETWEEN PHASES. THE MODEL OBTAINED HAS NUMEROUS APPLICATIONS: CIVIL ENGINEERING, AGRONOMY, HEAT STORAGE AND GEOTHERMICS.
