摘要
详细介绍并归纳多孔介质与木材领域内的传热传质理论研究概况,从中寻找出适合研究刨花对流干燥过程传热传质的方法。经过理论分析,提出可根据非平衡热力学理论和相平衡理论,建立一个描述刨花对流干燥时刨花外部对流传热传质和内部热、湿迁移过程的非平衡热力学模型。
The heat and mass transfer theory in the porous media and wood fields was studied, and introduced in detail to find a promising method in the process of particles drying with convection. Furthermore, according to un-equilibrium thermodynamics theory and phase equilibrium theory, an un-equilibrium thermodynamics model, which could describe the processes of the heat and mass transfer with convective drying outside the particles, and heat and moisture transfer inside the particles was given out.
