Moisture transfer

Since experimental investigations are rather expensive and of limited transferability, there is an urgent need for reliable heat and moisture transfer calculations . In order to study the influence of moisture transfer on the wall internal surface temperature, a coupled heat and moisture transfer transient model was proposed. The combined heat and moisture transfer finite (HAMT) solution algorithm is a completely couple one-dimensional, finite element, heat and moisture transfer. In addition to optimising for comfort and freedom of movement, good moisture management enables maximum performance.
