干燥过程中热质传递交叉效应的研究

摘要

针对雷柯夫建立在不可逆过程热力学原理上的传热与传质方程组，着重研究毛细多孔介质内传热与传质过程中的交叉效应.得出了非稳态干燥过程的理论解，并通过实验验证了其正确性,利用该模型分析了干燥过程中各因素对内部温度场和湿度场的影响以及交叉效应在干燥过程中的作用.%Presents the study on the cross-effect of heat and mass transfer of capillary porous media A.B.Luikov set up on the irreversible thermodynamics principle with the theoretical solution of unsteady drying process given and its validity verified though experiments, and analyses using the mathematical model the influence of all factors on temperature and moisture distribution and the cross-effect of heat and mass transfer during drying processes.
