In the process of heat and mass transfer in unsaturated porous media, the measurement and treatment for the "true" thermal conductivity is disputable due to the moisture migration. Therefor, the temperature and heat flux density are calculated for a typical porous unit of partially saturated packed cylinders in 2-Dimesional stagnant cases, and the effective thermal conductivity with different saturation is obtained. Results indicate, for general cases where heat conduction capability of solid is much higher than that of liquid and that of liquid is much higher than that of gas, thermal conductivity of porous media enlarges quickly with the increase of moisture saturation, but trends to smooth finally.

在非饱和含湿多孔介质传热传质的过程中,由于湿分迁移的存在,使得真实导热系数的测量和处理存在争议。为此,运用有限元方法,求解了二维稳态条件下非饱和含湿多孔体特征单元的温度和热流密度,给出了不同液相饱和度时的有效导热系数。结果表明,对于通常的导热能力固体远大于液体、液体远大于气体的情形,随着液相饱和度的增加,多孔介质的导热系数先迅速增加,然后逐渐趋于平稳。
