Numerical investigation of flow distribution and energy extraction in multi-fractured doublet Enhanced Geothermal Systems (EGS)

International Journal of Thermofluids
Enhanced Geothermal Systems (EGS) offer significant potential for sustainable, high-temperature energy extraction, yet their efficiency depends strongly on how fluid flow and heat transfer evolve within complex fracture networks.
