Machine learning‐assisted enhancement of soil thermal conductivity for improved performance of Earth–air heat exchangers under Iraqi climatic conditions
Earth–air heat exchangers (EAHEs) are widely used passive geothermal systems; however, their performance is often constrained by the low thermal conductivity of natural soil. The potential of iron filing waste (IFW) as a low‐cost, sustainable additive for modifying the thermophysical properties of the soil surround...
