The Humidity Field Approximation in Porous Materials

The Humidity Field Approximation in Porous Materials

Stať ve sborníku v databázi WoS či Scopus

During the identification of the humidity field through some of the non-destructive methods, e.g. by using microwave radiation, we obtain discrete data that are often negatively influenced by irregularities in the structure of non-homogeneous materials. While it can be recommended to disregard some of the divergences, some of them, conversely, are substantial. In order to execute the subsequent mathematical modeling of both the temperature and humidity fields, it is necessary to approximate such discrete fields. The approximation of the humidity field in porous materials has to adhere to numerous conditions. Non-negligible is also the required amount of cohesiveness. A suitable humidity field approximation then becomes the foundation for subsequent modeling, e.g. for determining the moisture conductivity coefficient of construction materials.
