The momentum equation is formulated using the linear Oberbeck–Boussinesq approximation to account for thermal and solutal density variations, while the concentration equation incorporates the Soret effect to represent thermally induced mass transport. Following non-dimensionalization, small perturbations are imposed on the base state to analyze instability. Linear stability theory determines the onset of stationary convection, whereas weakly nonlinear analysis characterizes heat and mass transfer. Flow structures and transport features are illustrated using streamlines, isotherms, and isosolutes. The results reveal that increasing the Jeffrey parameter destabilizes the system, emphasizing the role of fluid elasticity. For negative values of the solutal Rayleigh number, a negative Soret number delays convection by opposing thermal buoyancy, while a positive Soret number enhances instability. Transient Nusselt number behavior shows that higher Lewis number suppresses oscillations and accelerates system relaxation. Furthermore, positive solutal Rayleigh number enhances early mass transfer, whereas negative solutal Rayleigh suppresses it, and increasing relaxation time transforms streamlines from unicellular to bi-cellular when it greatly exceeds the retardation time.</p></div>","PeriodicalId":804,"journal":{"name":"Transport in Porous Media","volume":"153 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147796545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we focus on dispersive transport in porous media displaying spatially evolving heterogeneities, characterized by continuous spatial variations of their properties. Using upscaling, we derive the macroscopic transport equations for momentum and species dispersion and identify additional terms implying spatial derivatives of the porosity. While these terms do not influence the definition of the effective diffusion-dispersion tensor, we find that they remain in the closure problems for momentum transport and lead to the definition of two new effective permeability tensors. Length-scale considerations show that the closure problems for momentum transport can be simplified to facilitate their solving. To assess the validity of the derived model, we solve the macroscopic transport equations in a stationary dispersive mixing process: a <i>Y</i>-junction mixing chamber filled with porous media with spatially evolving heterogeneities. The consequences of distribution and strength of the porosity gradients on fluid velocity and concentration field are systematically compared to direct numerical simulations for various Péclet numbers, showing excellent agreement even in disordered porous media. Notably, we show that Péclet-dependent non-symmetric mixing layers can be produced using porous media with controlled porosity gradients.

Situations such as bank storage during river stage fluctuations, infiltration from surface sources, and drainage in shallow groundwater systems all fall within this setting and benefit from analytical solutions that capture these nonlinear effects. This exponent controls the degree of nonlinearity in the diffusion term and allows the model to represent a wide range of physical situations, from nearly linear flow to a strongly nonlinear transport, such as flows through concretes, forest soils, and filtration of polytropic gases. By extending the quadratic-profile approach to arbitrary nonlinearity, we obtain a family of exact solutions that describes both infiltration and drainage regimes within a single framework. The solution family also connects directly to two classical results: a traveling-front profile that appears under strong boundary fluxes and a selfsimilar mound that arises when the boundary flux vanishes.

Here, we demonstrate the workflow on an almost unexplored case, a consolidated sandstone with low pore-to-throat aspect ratio, and obtain a complex relative permeability hysteresis behavior, consistent with the few studies available for such media. The pore-scale simulations include primary drainage, followed by the main bounding hysteresis loop and scanning curves for secondary drainage and secondary imbibition. We also explore the impact of initial saturation after primary drainage on hysteresis and phase trapping. The relative permeability hysteresis is larger for the non-wetting phase than for the wetting phase, yet the extent of both decreases with increasing initial wetting-phase saturation. For the non-wetting-phase relative permeability, imbibition and drainage curves may cross, while scanning curves cross each other and exhibit a more significant hysteresis than the bounding loop. The role of trapped ganglia makes secondary processes different from primary. The behavior complies with hysteresis in phase connectivity, in which snap-off/coalescence breaks/recovers pathways. The results deviate significantly from the nested hysteresis loops seen for unconsolidated media and show that hysteresis in scanning curves cannot be neglected, indicating that flexible machine learning methods are better suited approaches than standard hysteresis models to implement this complex relative permeability behavior in reservoir simulators.</p></div>","PeriodicalId":804,"journal":{"name":"Transport in Porous Media","volume":"153 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11242-026-02308-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147649469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This gap limits mechanistic interpretation of injectivity evolution, pressure hysteresis, and working-gas loss in oil reservoirs converted to UGS. The present study develops an HPHT microfluidic visualization platform to observe three-phase dynamics in a sandstone-pattern micromodel at 85 °C under cyclic pressures of 10–29 MPa. The protocol reproduces key stages of UGS construction and operation, enabling real-time tracking of interfaces, phase redistribution, and connectivity. Weakly water-wet/mixed-wet conditions create persistent capillary heterogeneity, leading to capillarity-controlled fingering, snap-off, and immobilized oil films and ganglia during waterflooding, which subsequently constrain gas accessibility. During graded gas injection, intermittent pore-scale invasions and gas–water reconfiguration rapidly establish preferential gas pathways that dominate injectivity and cushion-gas development. Concurrently, sustained gas–oil contact promotes interphase mass transfer (gas dissolution into oil), manifested by oil swelling and enhanced oil mobility that locally assists remobilization and pathway evolution along the pressure trajectory. During withdrawal, wetting-phase re-imbibition partially collapses gas pathways, while flow reversal induces interfacial shear that redistributes wall-attached liquid films, together promoting irreversible gas trapping and connectivity hysteresis. In the first cycle, bulk gas saturation increases from ~ 40 to ~ 72%, while oil displacement efficiency (used solely as a diagnostic for three-phase redistribution) rises from ~ 12 to ~ 23% during injection and reaches ~ 26–27% at early withdrawal.

This assumption may not hold in certain technical and environmental applications, particularly with large temperature gradients, large differences in thermal properties, or high velocities. Local thermal non-equilibrium (LTNE) models aim to describe heat transfer processes when the LTE assumption may fail. We compare three continuum-scale models from the pore to the representative elementary volume (REV) scale. Specifically, dual-network and REV-scale models are evaluated against a pore-resolved model used as a reference in the absence of experimental results. Different effective models are used to obtain upscaled properties on the REV scale and to compare resulting temperature profiles. The systems investigated are fully saturated, consisting of one fluid and one solid phase. This study focuses on purely conductive systems without significant differences in thermal properties. Results show that LTE holds for low interfacial resistances. However, for large interfacial resistances, solid and fluid temperatures differ. The REV-scale model with effective parameters obtained by homogenization leads to similar results as the pore-resolved model, whereas the dual-network model deviates more due to fixed spatial resolution. Among the evaluated REV-scale formulations, only the homogenization-based approach captures the LTNE behavior, as it incorporates the interfacial heat transfer coefficient.

By integrating principles of plant hydraulics with advanced materials science, researchers have developed engineered systems that replicate key mangrove adaptations—including suberin-like barriers, aquaporin-mediated transport, and transpiration-driven negative pressure—to enable passive, energy-efficient freshwater production. Recent innovations in nanoporous membranes, biomimetic hydrogels, and artificial water channels have demonstrated the ability to generate capillary pressures sufficient to overcome osmotic pressures exceeding 400 bar, facilitating the desalination of hypersaline and contaminated water sources without external pumping. This review synthesizes recent advancements, highlighting the design and performance of leaf-, xylem-, and root-inspired components, while critically addressing persistent challenges, such as cavitation, membrane fouling, durability, and scalability. This review uniquely bridges recent, often disparate advancements across materials science, fluid dynamics, and biomimicry into a cohesive framework for the design of next-generation desalination systems. Emerging solutions—including gas-entrapping microtextured surfaces, slippery liquid-infused porous surfaces, and modular system architectures—are evaluated for their potential to enhance operational stability and real-world applicability. A novel set of six design rules is proposed, distilling biological principles into actionable engineering guidelines. The relative importance and design complexity of the three core functional components—roots, xylem, and leaves—are critically assessed, identifying the leaf as the fundamental engine and the root as the most design-intensive component. Although current implementations remain largely confined to laboratory settings, synthetic mangrove systems offer a promising pathway toward sustainable, decentralized water purification, particularly for off-grid and resource-limited environments. However, this promise must be tempered with realism: current operational lifespans are measured in hours to days, far short of the years required for industrial application, and substantial barriers in cavitation mitigation, scalability, and cost remain unresolved. By bridging biological insight with engineering innovation, this technology represents a transformative approach to next-generation desalination, aligning with global goals for water security and energy sustainability.</p></div>","PeriodicalId":804,"journal":{"name":"Transport in Porous Media","volume":"153 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147643021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we introduce a dual-continuum modeling framework that enables the simulation of fluid flow in both the original, main porous structure, referred to as porous matrix, and the newly formed salt structure. We present two modeling strategies: (1) a coupled-flow model that explicitly resolves mass and energy transport in both the matrix and salt continua, incorporating advective, diffusive, and filling-based exchange terms; and (2) a pseudo-flow model that assumes full saturation of the salt continuum and implicitly captures flow based on evaporative demand, improving computational efficiency. Both approaches reproduce expected saturation profiles, temperature distributions, and evaporation behavior. The resulting evaporation rates are increased, leading to a faster drying out of the porous medium compared to a single-continuum model. The coupled-flow model shows that the precipitated salt remains liquid-saturated for a longer period than the surrounding matrix, thereby sustaining upward water transport; however, its results are sensitive to the parameterization. By assuming full saturation of the precipitated salt, the pseudo-flow model yields the higher evaporation rates while also improving numerical stability.
