    inadequacy of mathematical model - hygrothermal prediction

    Despite the range and frequency of the problems encountered the current understanding of moisture transport mechanisms in timber is limited. However, due to the complexity of the moisture transfer phenomenon there has been much debate as to the methodology and form of an appropriate sorption model. The resulting publications, although interesting to the academic, often fall short of their potential due to, for example, a lack of experimental data, over-simplification, or unknown coefficients. In most cases, model builders use their own experimental data to fit their models. Problems arise where the sorption data are erroneous or inaccurate as the reliability is greatly affected by the accuracy of measurement of equilibrium moisture content and temperature.

    Nevertheless numerous mathematical models have been published to describe the wood moisture movement (Plumb 1985; Stanish 1986; Liu 1994; Pang 1996).
