利用CFD软件Fluent的前处理软件Gambit建立与实际系统相同的单U竖直地埋管换热器的三维非稳态传热模型,进行传热模拟仿真,通过得出的地能井与U型管中温度的变化图形来分析温度变化趋势,并与实验测试结果进行比较,结果表明,实验值和仿真结果很接近.这有利于掌握在没有预先埋好热电偶的情况下去观察地能井温度的变化.

@@@@Simulation the heat transfer by using the Gambit the pre-processing software of CFD to establish the three-dimensional unsteady heat transfer model which similarity with the actual system of single U buried vertical pipe of the heat exchanger, and compared with the experimental results through the graphical of well and U pipe to analysis the trend of temperature. The results agree well with the values measured experimentally and the simulation. This is in favor of grasping well the temperature of well under the condition of no thermocouples.
