Abstract
The thermal performance of a horizontal earth-pipe-air heat exchanger (EPAHE) was analyzed numerically using the Computational Fluid Dynamics (CFD) tool. In this way, it was analyzed the effects of pipe diameter, air flow velocities and different thermal properties of the soils in the thermal performance of the EPAHE system. The developed CFD model was simulated using commercial software and validated with numerical and experimental data. CFD analysis was executed using a steady-state three-dimensional numerical model with standard k-ε turbulence model. The results showed that the thermal performance of the EPAHE system was higher with a diameter of 0.1 m for the pipe, flow velocity of 2.5 m/s and with saturated sand soil.
