THEORETICAL AND COMPUTATIONAL INVESTIGATION OF SIMULTANEOUS HEAT AND MOISTURE TRANSFER IN BUILDINGS: < EVAPORATION AND CONDENSATION > THEORY.

Author(s) : KERESTECIOGLU A., GU L.

Summary

THE PAPER PRESENTS THE < EVAPORATION AND CONDENSATION > THEORY, A SET OF SPATIALLY DISTRIBUTED EQUATIONS FOR MODELLING DETAILED COMBINED HEAT AND MOISTURE TRANSPORT IN BUILDING SOLIDS. THE PHYSICAL MEANING OF VARIOUS TRANSPORT COEFFICIENTS AND THEIR INFLUENCE ON THE OVERALL TRANSPORT PHENOMENA ARE DISCUSSED. SAMPLE SIMULATIONS SHOWED THE AMOUNT OF MOISTURE ADSORPTION OR DESORPTION BY BUILDING MATERIALS TO BE SIGNIFICANT. TEMPERATURE EFFECTS ON MOISTURE TRANSFER WERE FOUND TO BE VERY IMPORTANT. EQUATIONS PREDICTED THE INTERNAL TEMPERATURE AND MOISTURE GRADIENTS SATISFACTORILY, FOR LIMITING CASES.
