| Abstract: |
|
Simultaneous one-dimensional heat and vapour transfer with condensation in a porous wall is analytically investigated. Spatially steady-state distribution of accumulated moisture, less than the critical content, is described. Closed-form analytical expressions for the temperature, condensation rate and moisture content are obtained. The presented model requires material properties which are relatively simple and easy to determine. The results of the paper are illustrated with an example of multilayer building wall under climatic conditions. |
