Development of a numerical workflow based on μ-CT imaging for the determination of capillary pressure-saturation-specific interfacial area relationship in 2-phase flow pore-scale porous-media systems: A case study on Heletz sandstone [PDF]

, 2016
In this case study, we present the implementation of a finite element method (FEM)-based numerical pore-scale model that is able to track and quantify the propagating fluid–fluid interfacial area on highly complex micro-computed tomography (μ-CT ...

Thermodynamically Consistent Modeling of Coupled Elastoplastic Geomechanics and Two‐Phase Flow With Capillary Hysteresis in Porous Media

International Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT We propose a unified constitutive framework for two irreversible processes governing coupled flow and geomechanics in porous media: capillary hysteresis in two‐phase flow and elastoplastic deformation. Extending our previous work that draws an analogy between capillary hysteresis and elastoplasticity theory, we introduce an additive ...

Reactive-infiltration instabilities in rocks. Fracture dissolution

, 2012
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surrounding rock matrix.

Review of artificial intelligence applications in geothermal energy extraction from hot dry rock

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 651-672, December 2025.
This paper systematically summarized the applications of artificial intelligence (AI) in hot dry rock (HDR) geothermal exploitation and discussed the limitations and opportunities. A novel intelligent HDR exploitation system was proposed to promote the development of HDR toward more efficiency, economy, and intelligence.

Multiphysics modeling of coupling compressed‐air energy storage‐thermal storage in salt caverns: An approach to insoluble sediment as heat reservoir feasibility analysis

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 777-791, December 2025.
This study investigates the feasibility of utilizing insoluble sediments in salt caverns for short‐ and long‐term thermal energy storage applications. The analysis revealed three key thermal characteristics of these sediments: (1) thermal shock resistance, (2) temperature differential compensation capability during air injection, and (3) high ...
