对流边界条件高强度快速传热传质研究

RESEARCH ON HIGH INTENSE AND RAPID HEAT AND MASS TRANSFER IN CONVECTIVE BOUNDARY CONDITION

在考虑非傅立叶效应和非斐克效应的基础上，对所建立的高强度快速传热传质的耦合方程进行了对流边界条件的数值模拟．结果表明：由于超常传热传质的耦合作用会造成多孔介质内部“局部增湿”现象，且温度和湿度的变化会出现滞后现象．

On the bases of Non-Fourier and Non-Fick effects, coupled equations of high intense and rapid heat and mass transfer are founded and made numerical simulation. The results show that because of coupled action between trans-normal heat and mass transfer, 'local humidity increase' phenomena will happen and the changes of temperature and humidity will lag in porous materials.
