Based on classical analysis and conclusive comments about variouskinds of drying models, a rigorously formulated and comprehensivetheoretical model is established to describe heat and mass transferduring constant rate and falling rate Periods in convective drying ofporous materials. The concept of iterative correction is introduced,and a corresponding numerical method is developed for the movingboundary problem in numerical simulations of drying processes. Thecalculation results for the drying of bricks show that the modelpresented is more precise than other models.
