The present work summarizes the results of several previous studies on moisture movement in wood during drying under isothermal conditions. A model of the wood drying taking into consideration coating of the surface of a specimen is presented in three‐dimensional‐in‐space (3‐D) formulation. The influence of the geometrical shape as well as surface coating degree of wood specimens from the northern red oak (Quercus rubra) on the drying dynamics is investigated. The conditions of usage of 2‐D moisture transfer model in contrast to 1‐D for accurate predicting of the drying process are described.
