A 1.5D soil-well coupled model studying heat transfer performance in coaxial geothermal wells

Coaxial geothermal wells enable “heat extraction without water extraction,” which helps avoid groundwater pollution and eliminates the need for reinjection in hydrothermal geothermal development. Using the finite element method, we develop a 1.5D soil-well coupled heat-transfer model for a coaxial g...
