Moisture transfer analysis during drying of slab woods

摘要

This article presents an analytical technique for determining the moisture diffusivities and moisture transfer coefficients for slab shaped woods subjects to drying process. The analysis of transient moisture diffu- sion is carried out on the basis of two important practical criteria: 0.1＜Bi＜100 and Bi＞100. The drying coeff- cients and lag factors and defined for wood-drying appli- cations and incorporated into the models. In order to verify the present models, the model results are compared with experimental measurements taken form the literature and good agreement was found.
