| 摘 要： | 针对热泵地埋管周围土壤内热湿耦合迁移特性开展研究，采用非饱和多孔介质三参数渗流物理模型，将地埋管温度边界与土壤温度边界进行耦合，利用FLUENT软件的UDF功能对地埋管和周围土壤进行耦合运算，得到非冻土条件下地埋管周围土壤水饱和度、压力和温度梯度的变化规律，数值模拟结果与现场测试结果进行对比，吻合较好．

| Abstract: | The research was carried on the heat and moisture transfer performance of soil around heat pump. A numerical model of unsaturated porous media was employed to couple the temperature bound- ary of buried pipe and soil. The extension of function User-Defined Function （UDF）, provided by FLUENT software, was used to simulate the variation of water saturation, pressure and temperature distribution. The analytic result mainly accords with the experimental result. |
