Heat Exchange in Tensile Fractures: an Experimental and Numerical Approach

Geothermal energy is a relatively sustainable energy source of which the essence is to extract heat from hot subsurface rocks. Circulating fluids serve as the transport agent of heat. The contact area between the fluids and the rocks is where the relevant heat transfer occurs, i.e., where the water is heated up. In some geothermal reservoirs,...

Algebraic Dynamic Multilevel Simulation of Coupled Flow and Heat Transfer in Heterogeneous Geothermal Reservoirs with Fluid-Rock Non-Thermal Equilibrium Effects

Accurate simulation of fluid flow and heat transfer in geothermal reservoirs is a crucial necessity for optimising energy extraction strategies. However, natural formations (including geothermal ones) extend large length scales (in the order of km), while their properties (e.g., heat and flow conductivity) can change in small (fine) scales (e.g....
