蓄热过程中非饱和土壤热湿迁移特性的数值研究

摘要

Based on the theory of the heat transfer of the porous media and mass transfer in unsaturated soil heat,the moisture transfer mathemati-cal model was established. Using Matlab software to calculate with the control volume method,gained the basic relationship of heat transfer mass mechanism and temperature and humidity field,provided reference basis for the optimization of underground regenerative/exothermic system.%基于多孔介质传热传质理论，建立了在蓄热过程中关于非饱和土壤热湿迁移的数学模型，采用控制容积法，利用Matlab软件对模型进行了数值求解，得到了基本的传热传质机理及温湿度场间的关联性，为优化地下蓄/放热系统提供参考依据。
