Summary: This study investigates the impact of thermal-active structures exchanging heat with the ground, analyzing one-dimensional problems and establishing dimensionless parameters to evaluate THM interactions and their evolution over time. Results show that in THM modeling of thermo-active retaining walls, the structural response is influenced by various factors including thermal expansion of soils, volumetric deformations due to pore water generation, and mechanical boundary conditions. Therefore, performing accurate THM analyses and estimating hydraulic and thermal properties correctly are crucial for ensuring the safe design of thermo-active structures.

Summary: This paper investigates the thermo-hydro-mechanical (THM) problem of layered porous media using the transformed differential quadrature method (TDQM). By transforming the governing equations in cylindrical coordinates and discretizing the temporal and spatial domains, the partial differential equations are converted into algebraic equations. Through the introduction of load conditions, boundary conditions, and continuity conditions, the matrix equation to solve the coupled THM problem is obtained. Case studies are conducted to verify the TDQM solution and discuss the influences of thermal and hydraulic parameters on the THM behaviors of layered porous media.

Summary: This study proposes a micromechanics-based thermo-hydro-mechanical model to capture the freezing behavior of porous media, considering the microstructure-dependent constitutive relation, thermo-hydro-mechanical conditions, and the origin of freezing deformation. A micromechanical upscaling approach is used to improve the physical understanding of freezing behavior. Comparisons with experimental and theoretical results indicate that the model is reliable for predicting freezing deformation of saturated and air-entrained porous media. The model provides insights into the freezing resistance mechanism of porous media by quantitatively analyzing the effects of freezing rate, liquid water transfer, and pore shape.

Summary: This study explores the adsorption mechanisms in unsaturated systems by analyzing flow, transport, and adsorption processes under different liquid saturation degrees through experimental and numerical simulation approaches. The results show that as the liquid saturation decreases, the mixing increases and the adsorbed mass reduces. The adsorption exhibits a nonlinear relationship with the liquid saturation, which can be attributed to the nonlinear variation of the volume fraction of the liquid phase.

Summary: This paper proposes a formulation based on the Water Mixing Approach to model solute transport in heterogeneous porous media. The formulation takes into account the scale dependence of dispersion and the separation of mixing from spreading. It introduces velocity as an independent variable, allowing concentration to depend on time, space, and velocity. The formulation, termed the Multi-Advective Water Mixing Approach, incorporates a new mixing term between velocity classes. Experimental results demonstrate the high accuracy of the formulation in both dispersion and mixing, with the mixing process exhibiting Markovianity in space despite being modeled in time.

Summary: Geological carbon storage is a crucial technology for achieving the net-zero emission target and climate change neutrality. Injected CO2 in geological formations undergoes chemical reactions with minerals, which can impact the properties of rocks and affect reservoir and wellbore integrity, injectivity, and sealing capacity. Laboratory experiments provide valuable insights into the short-term alteration mechanisms of rocks and are essential for understanding and upscaling the chemo-hydro-mechanical processes of CO2 storage.

Summary: Wormholes are conductive channels formed in highly soluble rocks, playing a crucial role in the sustainability of saline karst aquifers. The dynamics of wormholes depend on the hydrodynamic and geochemical conditions during formation, as well as the competition for flow. However, there is a lack of direct observation and quantification of wormhole dynamics. In this study, an experimental set-up was proposed to visualize and characterize the growth of multiple wormholes, providing insights into the changes in flow and transport behavior of aquifers.

Summary: Heat transport in fractured aquifers is influenced by the heterogeneity of flow velocity in the fracture system as well as the diffusive exchange between fluid and rock matrix. This study focuses on the impact of diffusive exchange on heat transport response, compared to solute transport governed by pure advective displacement. The behavior observed after the peak differs from matrix diffusion and is driven by the variability of velocity field and fracture aperture field. Theoretical models are derived to predict these pre-asymptotic tails under extreme cases related to specific network structures.

Summary: Post-injection seismicity at the enhanced geothermal system of Basel, Switzerland, was caused by poroelastic stress relaxation of stabilized faults during injection. Numerical simulations of the stress field applied on a fault network indicated that faults located near the injection well failed due to pore pressure buildup, while distant faults were affected by poroelastic stressing and shear-slip stress transfer. After injection stopped, the poroelastic stress relaxation led to the immediate rupture of previously stabilized faults.
