Heat transfer analysis of deep coaxial geothermal heat exchangers: Insights into heat-flux distribution on borehole wall

Deep geothermal heat exchangers (DGHEs) have emerged as a potential approach to exploiting geothermal energy as a stable high-temperature heat source for ground-coupled heat pumps. This study aimed to offer insights into the heat transfer of DGHEs by systematic numerical simulations. This study firs...
