ABSTRACT

This article proposes a rapid way to use experimental measurements of mass transferminus;mass diffusivity and permeability to air−to compute two global morphological parameters of wood: tortuosity factor and equivalent pore radius. The device conceived for measuring mass diffusing in steady state is a specific vaporimeter PVC-CHA. For air permeability, another device, ALU-CHA, has been developed. Using a simple structure modeling of the porous medium to analyze the transport phenomena, the two global morphologic parameters cited have been fitted. Spruce, pine, beech, and teak are tested through samples (about 24) of these species, sawed for longitudinal, tangential, and radial directions flows. Some of the measurements are exploited. The results obtained for tortuosity and equivalent pore radius have been compared with those found in the anatomical literature, and a good concordance has been observed.
