摘要

Heat and water vapor transfer within a fiberglass insulation filled cavity (135mmx600mm) is investigated numericaly and experimentally during air infiltration. A forced, two-dimenssional cold and dry air flow is introduced from the cold side to warm side throught he fiberglass insulation. The initial condition for the fiberglass insulation is the insulation first experienced a period of air exfiltration in which moist and warm air flow fowed from the warm to the cold side. Tis is followed by air infiltration where cold dry air flows from the cold to the warm side. The heat and mass transfer with trosting effects within the porous insulation are modeled for two-dimensional air flow with transient heat and moisture transfer. this model is validated using data for temperature and moisture distribution and heat flux on the cold and warm sides.
