Abstract: Sorption hysteresis of wood is modelled using a modification of the independent domain approach by taking into account capillary condensation as a hysteretic process and film adsorption as a non-hysteretic process. A change in moisture content in the porous material is the result of the behaviour of an assemblage of different sorption domains, described by a distribution function. A new description of the integrated distribution function is introduced, which can be identified from measured main adsorption and primary desorption curves. The model is validated by simulating the sorption moisture behaviour of wood in dynamic sorption tests for the three orthotropic directions.
