In the present study, a mathematical model with a moving evaporation interface was constructed to quantitatively assess the mechanisms of moisture and heat transfer during superheated steam wood drying. In this model, the unsaturated Darcy flow of free water was considered as Fick diffusion. By modeling the interface evaporation rate and volume evaporation rate, the model (1) characterized the moving water evaporation interface; (2) quantified the dynamic alterations of wet/dry regions; and (3) predicted the change regularity of real-time tempe...
