Abstract:

Precision has been evaluated of the 10 most often used wood sorption models, available in literature, for the calculation of the equilibrium moisture content of wood given a change in temperature within the range from 0 °С to 200 °С and in the relative humidity of the surrounding air environment from 0% to 100%. Based on the results of the critical analysis, an argumentative selection has been done of the models that can be purposefully used for the computer determination of wood equilibrium moisture content in contemporary systems for model-based or model predictive automatic control of different processes of hydrothermal treatment of wood and wood materials. With the help of these models, diagrams have been created for precise determination of wood equilibrium moisture content. The established high precision of both the Simpson and Ray et al. models and the Garsía model, which we have refi ned, makes them user friendly for model-based or predictive automatic systems and other engineering applications in the respective temperature ranges specified in the paper.
