Experimental Study of the Effect of Different Well Flow Quota on Groundwater Thermal Flow Transport Variation

In earth energy utilization, different multi-well flow match modes determine the different groundwater thermal flow transport characteristic. In this study, a laboratory experimental system was designed and set up to study the aquifer heat transfer performance and temperature field variation in different multi-well flow match modes. The experimental results show that under the condition of certain total flow rate, different multi-well flow match modes have great effects on the change of groundwater seepage field and temperature field. The bigger the flow rate, the greater the heat transfer per unit time and temperature field variation, and the closer the occurrence time between cold water frontal and cold water effect frontal, which is not conducive to the active control of aquifer temperature field.
