To create a model of beech wood drying in the hygroscopic range, knowledge of longitudinal permeability and diffusivity parameters of wet air in wood is needed. These data were obtained using a Wicke-Kallenbach-cell running in an open system and crossed either by an inert gas (nitrogen) or by two streams of two inert gases (helium and nitrogen), that prevent the adsorption phenomena in wood. Taking into account the relations between apparent and molecular diffusivities, the diffusivities of steam could be calculated from those of helium. Longitudinal diffusivity and permeability increase slightly with the moisture content of wood; the average values obtained at the ambient temperature (20°C) for the axial diffusivity (8. 1. 10 −6  m 2 /s) and for the axial permeability (2. 2. 10 −11  m 2 ) are compatible with those reported in the literature for this species.
