EVALUATION OF WOOD SORPTION MODELS FOR HIGH TEMPERATURES
Marcia Vidal Bastías | Alain Cloutier
Seven wood sorption models available in the literature were parameterized for prediction of equilibrium moisture content for temperatures up to 220°C. The criterion used to evaluate the models is the uncorrected sum of squares of differences between the predicted equilibrium moisture content and experimental values published in literature for temperatures between 0°C and 160°C. The results show that the Malmquist model gave the best overall fit to experimental data for the relative humidities considered (40%, 52%, 65%, 75% and 85%). However, the García model performs better for temperatures between 110°C and 155°C at a relative humidity of 85%. Therefore, the choice of the sorption model depends on the specific hygrothermal conditions required by the user.
