Abstract

The paper is to discuss the thermal phenomena of the supercritical CO2 in the geothermal reservoir for the enhanced geothermal system. The transient heat transfer model conjugated with the Brinkman model of employed by the finite element package is used to obtain the dynamic and thermal behavior in the porous medium. The different pressure of the reservoir, the various inlet volumetric flow rate are discussed. The results show that the inlet volumetric flow rate results in the temperature difference between the wall and working fluid on the exit apparently. It can be predicted that the heat extraction will increase as the volumetric flow rate decreases. In addition, the suitable operated pressure will reach the maximum heat extraction for the reason of property of supercritical CO2.
