Abstract

Abstract: An analytical method by means of the transfer function is proposed to study the processes of coupled heat and moisture transfer in walls based on Luikov's equations.The calculations for coupled heat and moisture transfer in the fiberglass slab are conducted to obtain the transient distributions of temperature and 1-D distributions of moisture accumulation rate using the mentioned method. The results agree with the measured data, and show that the mathematical equations and the solving method are reasonable.

Key words: porous media, coupled heat and moisture transfer, transfer function
