In this paper, the wood drying process is investigated theoretically under transient conditions. The governing equations of heat and mass transfer in wood are presented. The finite elements method is used to solve the set of governing equations by means of a simulation program. For verification of the present model, the wood model is executed within the TRNSYS program with experimental data of wood drying experiments conducted at Wood Research Institute of Munich, Germany, and with previous theoretical works. For steady state and transient conditions, the computational results show considerable agreement with previous experimental and theoretical works.
