soil thermal conduction

To determine extent of the effect of groundwater advection on U-type vertical underground heat exchangers, based on a mathematics model considering thermal conduction and groundwater advection, utilizes an overall solution to obtain the whole temperature field including fluid in pipe, pipe wall and surrounding soil.

为确定地下水渗流对U型地下埋管换热器的影响，基于热渗耦合作用下的数学模型，采用整体求解方法求得管内流体、地下埋管换热器及周围土壤的温度场数值解。
