A Sorption Hysteresis Model For Cellulosic Materials

Henrik Lund Frandsen, Lars Damkilde

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


The equilibrium concentration of adsorbed water in cellulosic materials is dependent on the history of the variations of vapor pressure in the ambient air, i.e. sorption hysteresis. Existing models to describe this phenomenon such as the independent domain theory have numerical drawbacks and/or imply accounting for the entire history variations of every material point. This paper presents a sorption hysteresis model based on a state formulation and expressed in closed-form solutions, which makes it suitable for implementation into a numerical method.
