The paper presents a numerical procedure for the simulation of heat and fluid flow in a low enthalpy geothermal energy system, using a generalised model for porous media flow and an equivalent porous medium approach for macroscopic description of the heat exchanger. The results obtained are validated against the experimental data available for a geothermal reservoir in the island of Ischia in Italy, which were available from previous work of one of the authors. The comparison shows that the proposed procedure can be successfully used for the simulation of this type of problems.

Abstract
The paper presents a numerical procedure for the simulation of heat and fluid flow in a low enthalpy geothermal energy system, using a generalised model for porous media flow and an equivalent porous medium approach for macroscopic description of the heat exchanger. The results obtained are validated against the experimental data available for a geothermal reservoir in the island of Ischia in Italy, which were available from previous work of one of the authors. The comparison shows that the proposed procedure can be successfully used for the simulation of this type of problems.File in questo prodotto:
