A mathematical model for studying the heat and mass transfer in wood during its modification is derived. The model is constructed on the basis of a continual approach within mechanics of heterogeneous medium. Wood is considered as transversal-isotropic unsaturated three-phase system. A numerical experiment for investigating the influence of phase transition and capillary effect on the moisture field is carried out. The analysis of heat and hydrodynamic regimes is conducted. It is shown that during a technological process of wood modification modeling it is necessary to calculate the coupled heat and mass transfer.
