多孔介质快速干燥过程中热质耦合效应的研究

COUPLED HEAT AND MASS TRANSFER IN POUOUS MEDIA DURIING RAPID DRYING PROCESS

本文针对一维多孔介质的第一类边界条件，对高强度快速干燥条件下热质交换的普遍微分方程组进行求解。研究了高强度快速干燥过程中多孔介质内部传热传质之间的相互耦合现象以及初始边界条件的变化对热质传递的影响，为多孔介质内部温度场和湿度场的控制奠定理论基础。

In this paper, heat and mass transfer under the first boundary condition during high intensive and rapid drying process is analysed and the general differential equation group is resolved. It researches the effect of boundary condition Change on heat and mass transfer by means of analysing the coupled heat and mass transfer phenomena. It can supply the theory foundation for the control over temperature and humidity fields in porous media.
