摘要：The heat and moisture transfer model above fiber saturation point (FSP) has been developed based on volume averaging theory in the last paper. It's numerical solutions under adequate initial and boundary conditions a re obtained by adopting fully implicit finite difference method and MATLAB software in this paper. This paper verifies experimentally the model and describes theoretically the changeable and distributional patterns of moisture content and temperature in the process of microwave drying of wood. The numerical solutions show that the microwave drying process may be divided into two stages which are the stage of increasing drying rate and the stage of constant drying rate. And there are no significant moisture and temperature gradients that are indicated along thickness of wood in the process of wood drying.
