A simplified coupled hydro-thermal model for enhanced geothermal systems

The modelling of fluid flow and heat transfer under coupled conditions remains a challenging issue particularly for industrial-scale enhanced geothermal systems. This paper proposes a simplified approach to model the coupled hydro-thermal system for hot dry rock geothermal applications. The simplified heat exchange model is based on the first principle of heat exchange between two media (fluid and rock) and Newton’s law of cooling so that it...
