Analyses of fracturing and thermal performance of fractured reservoirs in engineered geothermal system (EGS) are extended from a depth of 5 km to 10 km, and models for flow and heat transfer in EGS are improved. Effects of the geofluid flow direction choice, distance between fractures, fracture width, permeability, radius, and number of fractures, on reservoir heat drawdown time are computed. T...

The Divertor Tokamak Test (DTT) facility, a fully superconducting nuclear fusion reactor being built in Italy, will contribute to address the power exhaust problem EU DEMO perspective. A lot of flexibility operation be demanded machine, which should capable tackle also severe transients such as plasma disruptions. In this work, 4C thermal-hydraulic code is used compute temperature margin during...

This paper presents a coupled thermal-hydraulic-mechanical (THM) model for simulating failure processes in geological media. The coupling between stress/strain and heat transfer describing how thermal expansion affects stress is based on the theory of thermo-elasticity. Additionally, fluid flow pore-pressure governed by Biot's consolidation theory. Stress/strain-dependent porosity/permeability/...
