The main purpose of this paper was to investigate an experimental and theoretical analysis of
heat and moisture transport behavior in wood during convective drying process. A convective drying
cell was used to follow the measurements of the water content of samples subject to hot air flow in
longitudinal and transverse moisture transfer of wood. The effects of drying conditions such as
drying air temperature, air velocity and ambient relative humidity on the drying characteristics of
wood has been investigated. The constants drying and diffusion coefficients of the drying model,
which control the drying rate of wood, were determined from fitting the model against the
experimental drying curves. Results showed that, drying kinetic behaviour of the longitudinal
diffusion is very significant than the transverse one. The moisture content increased with increase in
drying air temperature and air velocity but decreased with time. From the curves of moisture flow
evolution versus moisture ratio, convective heat and mass transfer coefficients have been evaluated
and compared with values obtained from the literature and existing correlations.
