Abstract

Earlier studies by the first author have shown that the single-phase finite element modelling of moisture diffusion in untreated wood is an efficient tool to simulate the moisture transport in wooden components of buildings sheltered from rain (Fragiacomo et al. 2011). An extension of this approach, that takes into account the effect of rain in thermally modified products, is proposed in the present paper. The sorption isotherms used in the model are measured at dif-ferent temperatures above zero degrees Celsius within this research. In addition, the diffusion coefficient includes the contribution of free water in wood above the fiber saturation point. A case-study of thermally modified wood is numerically analyzed and the results in terms of moisture contents are compared with data taken from a previous research (Metsä-Korteläinen et al. 2011). In future work, the proposed moisture transport model will be combined with well-assessed models for wood decay (Brischke and Meyer-Veltrup 2016).
