The author proposes a model for drying processes of wet deformable porous solids. It is based on the theory of balance equations and on principles of irreversible thermodynamics. During the drying process, the materials shrink and change their size and shape. Consequently, there appear internal stresses which may even cause the fracturing of the body, and also the transport of heat and moisture takes place. Both features are examined in the article: the first part is quite general, in the second part a simplified model is presented where reasonable assumptions for many practical applications are used. The analysis of the convective drying of a ceramic cylinder is included as an illustration of the theory.
