Freezing and thawing of soil moisture is accompanied with a series of physical processes in seasonal freezing-thawing areas, such as moisture transfer and heat exchange.
在季节性冻土分布区，土壤水分的冻结和融化必将会伴随着热量交换、水分迁移等物理过程。
Soil heat flux plays an important role in energy flux exchange between land and atmosphere, especially in arid and semi-arid region.
土壤热通量在地表能量交换中扮演着重要角色，干旱半干旱区土壤热通量更加重要。
With the help of FLUENT software, the numerical simulation of the heat exchange between the multiple well heat system and the surrounding soil is conducted in this paper.
本文利用FLUENT软件对井群换热器与周围土壤的换热过程进行了数值模拟研究。
