THERMAL DIFUSIVITY AND MASS TRANSPORT IDENTIFICATION IN A POROUS MEDIA
ABSTRACT. THIS WORK DEVELOPS A TECHNIQUE OF SIMULTANEOUS OBTAINING OF THERMAL DIFFUSIVITY AND AND MASS TRANSPORT IN A HUMID POROUS SAMPLE. THE GOVERNING EQUATIONS OF THE TRANSPORT OF ENERGY AND MASS FOR A HUMID POROUS MEDIUM NOT SATURATED ARE OBTAINED. THE OPTIMIZATION TECHINIQUE BASED ON THE METHOD OF THE CONJUGATED DIRECTIONS IS USED TO IDENTIFY THE THERMAL AND MASS TRANSPORT PROPERTIES. THE EXPERIMENTAL MEASURE OF TEMPERATURE AND MASS ARE NUMERICALLY SIMULATED. THE RESULTS INDICATE THE GREAT POTENTIALITY OF THE OPTIMIZATION TECHNIQUE IN THE THERMAL AND MASS PROPERTIES IDENTIFICATION IN HUMID POROUS MEDIA
KEY-WORDS: OPIMIZATION – POROUS MEDIA – PARAMETER ESTIMATION
