Abstract

The influence of the geometrical shape of a wood specimen on the dynamics of drying under isothermal conditions is investigated in this research. Polynomials describing the dependence of half-drying time on the ratio of the area to the perimeter of the transverse section of extremely long specimens of northern red oak Quercus rubra, are presented for drying from above the fiber saturation point. This paper describes the conditions of usage of a two-dimensional moisture transfer model in contrast to the one-dimensional model for accurate prediction of the drying process. The dependence of halfdrying time on the ratio of the volume to the surface of the specimens in the shape of a rectangular parallelepiped has been investigated using a three-dimensional moisture movement model. Polynomials describing that dependence are presented.
