A three dimensional model for heat and mass transfer in convective wood drying

Abstract

A three-dimensional model is proposed to describe the heat and mass transport process in drying of wood. The model is based on conservation of mass and energy and uses constant parameters obtained by comparing experimental data with numerical results. The model uses parameter values from literature. Experimental results obtained for temperature profiles during drying of a block of beech wood are compared with the model results. Satisfactory agreement is obtained over a range of drying air temperatures and velocities.
