Heat Transfer and Fluid Transport of Supercritical CO2 in Enhanced Geothermal System with Local Thermal Non-equilibrium Model

Modeling Geochemical Processes in Enhanced Geothermal Systems with Co2 as Heat Transfer Fluid

The concept whereby heat is recovered from a geothermal reservoir by replacing the native aqueous phase with essentially pure high-pressure carbon dioxide as the working fluid is referred to as an Enhanced Geothermal System with CO2 (EGSCO2). The concept has yet to be tested in the field, and the chemical consequences, both within the reservoir itself, and at its periphery, are not fully unders...

Numerical Studies of Fluid-rock Interactions in Enhanced Geothermal Systems (egs) with Co2 as Working Fluid

There is growing interest in the novel concept of operating Enhanced Geothermal Systems (EGS) with CO2 instead of water as heat transmission fluid. Initial studies have suggested that CO2 will achieve larger rates of heat extraction, and can offer geologic storage of carbon as an ancillary benefit. Fluid-rock interactions in EGS operated with CO2 are expected to be vastly different in zones wit...

Numerical Investigations of Heat Transfer in Phase Change Materials (pcms) Using Non-thermal Equilibrium Model

Phase change materials (PCMs) are drawing increasing attention of researchers nowadays, and they play a pivotal role in thermal energy storage (TES) used in renewable energy resources applications, since these renewable energy, such as solar energy, wind energy and tidal energy, are intermittent and not available at any time. However, most of PCMs suffer from low thermal conductivities prolongi...
