Convective heat and mass transfer in moisture desorption of oak wood by introducing characteristic transfer coefficients

Abstract

This paper presents the effect of forced convective heat and mass transfer coefficients on the predictive ability of a dynamic isothermal set of coupled partial differential equations. The analysis showed that the two coefficient two-dimensional model, resulted in a very good prediction off:he experimental data. The concept of experiment involves: six temperatures, six relative air humidities and three values of circulation velocity. Dimensions of oak (Quercus petraea) wood samples were 250x80x25mm. The experimental installation, designed and constructed for this study, enables the drying process of relatively small samples to be similar to the drying process of real timber.
