摘要
本文以5m间距的布管方式为例,使用FLUENT软件对等间距及非等间距两种布管方式进行数值模拟,研究比较存在地下水渗流时非等间距布管方式对土壤温度场以及管壁热通量的影响.模拟计算结果表明,存在地下水渗流时非等间距的布管方式能够明显提高井壁的热通量,而对土壤的平均温度影响较小.
Based on 5m piping as an example, using the FLUENT software to simulate two ways of piping non- equidistant piping and equidistant piping,studying the impact of non- equidistant piping on soil temperature field and the wall heat flux under the condition of groundwater seepage. The simulation results show that the non- equidistant piping system can significantly improve the wall heat flux in the presence of groundwater seepage, while the influence on the average temperature of the soil is small.
