Multiscale modeling of coupled thermo-hydro-mechanical analysis of heterogeneous porous media

FEM‐based dual length‐scale simulation of hydrothermal ore‐forming systems involving convective flow in fluid‐saturated porous media

“…It should be pointed out that not only can nonlinearly coupled problems involving multiple physical processes be widely encountered in hydrothermal ore-forming systems, but also they can be broadly found in enhanced geothermal systems. [12][13][14][15][16][17][18][19][20] For example, to computationally simulate an enhanced geothermal system, a nonlinearly coupled problem involving heat transfer (i.e., thermal), pore-fluid flow (i.e., hydraulic) and rock deformation (i.e., mechanical) processes has been extensively considered in recent years. [12][13][14][15][16][17][18][19][20] However, compared with simulating enhanced geothermal systems, chemical reaction processes must be considered in the computational simulations of hydrothermal ore-forming systems.…”

Otherwise, an ore deposit cannot be quantitatively evaluated in a hydrothermal ore-forming system.…”

An enriched mixed finite element model for the simulation of microseismic and acoustic emissions in fractured porous media with multi‐phase flow and thermal coupling

“…Several papers have been published recently on the topic of fractured and non-fractured porous media with single-and multi-phase fluid flow with potential application in geomechanics. [4][5][6][7][8][9] Several numerical models have been proposed over decades for simulation of porous media with multi-phase flow. Depending on the focus of the projects and objectives, the reported works have limitations and restrictions.…”

“…Simulation of groundwater contamination by industrial chemicals and hydrocarbons in applications like waste injection, modelling of steam and water injection in reservoir stimulation processes for enhanced recovery, and seismic and slope stability analysis in porous formations are only a few to be noted. Several papers have been published recently on the topic of fractured and non‐fractured porous media with single‐ and multi‐phase fluid flow with potential application in geomechanics 4–9 …”
