UNSTEADY HEAT AND MASS TRANSFER WITH PHASE CHANGES IN AN INSULATION SLAB: FROSTING EFFECTS.
Author(s) : TAO Y. X., BESANT R. W., REZKALLAH K. S.
Type of article: Article
Summary
MOISTURE AND FROST ACCUMULATION IN A GLASS-FIBER SLAB ARE ANALYZED, USING A ONE-DIMENSIONAL, TRANSIENT, VAPOUR DIFFUSION MODEL WITH PHASE CHANGES AND VARIABLE PROPERTIES. THE COLD SINK BOUNDARY IS IMPERMEABLE AND SUBJECT TO A TEMPERATURE BELOWTHE TRIPLE POINT OF WATER WHILE THE OPPOSING WARM BOUNDARY IS OPEN TO A CONVECTIVE MOIST AIR. THE NUMERICAL RESULTS ARE PRESENTED FOR MOISTURE/FROST ACCUMULATION UNDER VARIOUS CONDITIONS. THE MOTION OF THE FROZEN BOUNDARY IS PRIMARILY GOVERNED BY THERMAL DIFFUSION. THE EFFECTS OF MOISTURE/FROST ACCUMULATION ON THERMAL PERFORMANCE ARE ALSO DISCUSSED.
