It is often assumed that using stratified patterns models capture adequately two-phase flow in fractures. However, recent studies indicated that a broader range of flow behaviors may occurs. This paper explores the impact of aperture and wettability on relative permeability in three-dimensional Berea fractures displaying moderate topological fluctuations. Using Lattice Boltzmann Method (LBM) simulations, we identify two distinct permeability regimes: at high apertures, permeability behavior aligns with that of parallel planes, while at low apertures, permeability decreases linearly due to fluid interactions with fracture surfaces. In weakly wet fractures, anomalous relative permeability behavior arises within specific aperture ranges, linked to the emergence of distinct flow structures. This phenomenon is primarily driven by interfacial tension, while wettability affects its onset, particularly at intermediate apertures. Furthermore, in non-wet fractures, fluid segregation at high apertures is governed by viscosity contrasts, where higher-viscosity fluids tend to flow more centrally, resembling Poiseuille flow. The results are particularly relevant to oil and gas recovery, highlighting the need for further investigations into interfacial tension effects in gas–liquid systems to enhance predictive models for fluid transport in fractured reservoirs.
通常认为,使用分层模式模型可以充分捕捉裂缝中的两相流。然而,最近的研究表明,更广泛的流动行为可能会发生。本文研究了具有中等拓扑波动的三维Berea裂缝的孔径和润湿性对相对渗透率的影响。利用晶格玻尔兹曼方法(LBM)模拟,我们确定了两种不同的渗透率状态:在高孔径下,渗透率行为与平行平面一致,而在低孔径下,由于流体与裂缝表面的相互作用,渗透率呈线性下降。在弱湿裂缝中,在特定孔径范围内会出现异常的相对渗透率行为,这与不同流动结构的出现有关。这种现象主要由界面张力驱动,而润湿性影响其发生,特别是在中间孔径处。此外,在非湿裂缝中,大孔径处的流体分离受粘度差异的控制,其中高粘度流体倾向于更集中地流动,类似泊泽维尔流。该研究结果与油气采收率特别相关,强调了进一步研究气液系统界面张力效应的必要性,以增强裂缝性储层中流体运移的预测模型。

In the geological storage of hydrogen and carbon dioxide in underground salt caverns, the water-injected salt dissolution technology is widely applied in the expansion of salt caverns. During the salt dissolution, a variety of minerals with different properties are often involved, and there are obvious competitive interactions among them. This competition is primarily manifested in differences in diffusion rates, dissolution rates, and ionic concentration equilibrium constraints. In this study, we developed a lattice Boltzmann model, taking into account the competitive dissolution mechanisms of different minerals under the constraint of ion equilibrium. The model was used to investigate permeability changes of porous structure under various injection velocities and different combinations of minerals. The results reveal that whether the physical properties of binary minerals vary greatly or not, such as reaction rate and diffusion rate, the impact of competitive dissolution cannot be ignored. And as the injection rate increases, the influence of the competitive dissolution effect on the pore structure evolution becomes greater. This research provides theoretical insights into binary minerals' competitive dissolution mechanisms and references for its applications in fields such as environmental science, resource development, and chemical engineering.
在地下盐洞地质储氢和二氧化碳中,注水溶盐技术在盐洞扩展中得到了广泛应用。在盐的溶解过程中,往往涉及多种不同性质的矿物,它们之间存在明显的竞争相互作用。这种竞争主要表现在扩散速率、溶解速率和离子浓度平衡约束的差异上。在这项研究中,我们建立了一个晶格玻尔兹曼模型,考虑了不同矿物在离子平衡约束下的竞争溶解机制。利用该模型研究了不同注入速度和不同矿物组合下孔隙结构渗透率的变化。结果表明,无论二元矿物的物理性质(如反应速率和扩散速率)是否变化较大,竞争溶解的影响都不可忽视。随着注入速率的增加,竞争溶解效应对孔隙结构演化的影响也越来越大。本研究为二元矿物竞争溶解机理的研究提供了理论依据,为二元矿物在环境科学、资源开发、化工等领域的应用提供了参考。

Dealing with environmental flows poses significant challenges, particularly when it comes to accurately predicting mass and heat exchanges between the atmosphere and a variably saturated porous medium. In this work, we develop a non-isothermal, two-phase, two-component porous medium model equipped with physically based boundary conditions that incorporate the influence of free-flow conditions on soil evaporation and the resulting geothermal heat flux. This approach enables the use of average parameters to describe the free-flow domain, thus avoiding the need to explicitly simulate atmospheric flow while maintaining accuracy in both evaporation estimation and subsurface dynamics.
The model is validated against well-documented laboratory-scale experiments from the literature, covering a range of free-flow conditions and soil properties. It is then employed to assess the impact of soil drying dynamics on the retrievable geothermal heat flux across different soil types. The results demonstrate distinct thermal responses strongly linked to soil saturation behavior. A comparative study across different soil types and water table depths, complemented by a sensitivity analysis of free-flow parameters, reveals two distinct regimes. For shallow water tables, free-flow properties dominate, allowing for simplified groundwater modeling. In contrast, for deeper water tables, the influence of free-flow parameters becomes negligible, and a detailed representation of groundwater flow-including evaporation-is essential. The proposed approach enables accurate modeling across both regimes without the need to simulate the entire free-flow domain.
处理环境流动带来了巨大的挑战,特别是当涉及到准确预测大气和可变饱和多孔介质之间的质量和热交换时。在这项工作中,我们开发了一个非等温、两相、双组分多孔介质模型,该模型配备了基于物理的边界条件,其中包括自由流动条件对土壤蒸发和由此产生的地热通量的影响。这种方法可以使用平均参数来描述自由流域,从而避免了明确模拟大气流动的需要,同时保持了蒸发估计和地下动力学的准确性。该模型通过文献中充分记录的实验室规模实验进行了验证,涵盖了一系列自由流动条件和土壤特性。利用该模型评估了土壤干燥动态对不同土壤类型可回收地热通量的影响。结果表明,明显的热响应与土壤饱和行为密切相关。一项跨不同土壤类型和地下水位深度的比较研究,加上对自由流动参数的敏感性分析,揭示了两种不同的制度。对于浅层地下水位,自由流动特性占主导地位,允许简化地下水建模。相比之下,对于较深的地下水位,自由流动参数的影响变得可以忽略不计,地下水流动的详细表示——包括蒸发——是必不可少的。所提出的方法可以在不需要模拟整个自由流域的情况下实现跨两个区域的精确建模。

Coastal waters face continuous threats from inland pollution sources, such as rivers, torrents, and wastewater discharges. These sources pose significant challenges to water quality management. To address the complex dynamics of pollutant transport and dilution in these environments, we introduce a scale-adaptive Expected Mass Fraction (EMF) framework. This framework enables the quantification and mapping of contaminant dilution through a flexible spatial representation, adaptable to arbitrary scales and tailored to specific water quality assessment needs. By combining Lagrangian particle tracking, stochastic ensemble analysis, and spatially integrated concentration statistics, the framework offers a comprehensive tool for evaluating the auto-purification potential of coastal waters. Applied to the Kaštela Bay and Brač Channel in the Eastern Adriatic Sea, the methodology captures the effects of distinct hydrodynamic events – Bora and Sirocco – on pollutant dispersion. Results reveal significant variations in contaminant transport patterns. Bora events exhibit localized surface spreading, while Sirocco events drive extensive horizontal and vertical dispersion. The proposed Auto-Purification Potential (APP) index consolidates these complex dynamics into a region-oriented map, providing a compact and accessible visualization of auto-purification potential. Such a visualization can support public awareness and informed decision-making in coastal water quality management. This study advances the application of EMF concepts to complex hydrodynamic environments, demonstrating its adaptability to diverse spatial scales. The findings provide a foundation for effective pollution monitoring and management strategies in coastal water ecosystems and offer the potential for broader applications in other environmental systems.
沿海水域面临内陆污染源的持续威胁,如河流、激流和废水排放。这些来源对水质管理构成重大挑战。为了解决这些环境中污染物迁移和稀释的复杂动力学,我们引入了一个自适应尺度的期望质量分数(EMF)框架。该框架通过灵活的空间表示实现污染物稀释的量化和制图,可适应任意尺度并根据特定的水质评估需求量身定制。通过结合拉格朗日粒子跟踪、随机集合分析和空间集成浓度统计,该框架为评估沿海水域的自净化潜力提供了一个全面的工具。该方法应用于东亚得里亚海的Kaštela湾和布拉斯海峡,捕捉了不同的水动力事件(Bora和Sirocco)对污染物扩散的影响。结果揭示了污染物运输模式的显著变化。Bora事件表现出局部的表面扩散,而Sirocco事件则表现出广泛的水平和垂直扩散。提出的自动净化潜力(APP)指数将这些复杂的动态整合到一个面向区域的地图中,提供了一个紧凑且易于访问的自动净化潜力可视化。这种可视化可以支持公众对沿海水质管理的认识和知情决策。本研究推进了电磁场概念在复杂水动力环境中的应用,展示了其对不同空间尺度的适应性。研究结果为沿海水域生态系统的有效污染监测和管理策略提供了基础,并为在其他环境系统中更广泛的应用提供了潜力。

Reservoir flow properties are crucial for sustaining the magnitude and effectiveness of compressed gas energy storage in aquifer. Although changes in flow properties due to CO2 injection have received attention, the impact of compressed air injection-induced geochemical reactions on flow properties has been overlooked. This study presents a series of controlled experiments with different reaction conditions to reveal the effects of pore-scale mechanisms of geochemical reactions on pore structure and flow properties. Although air injection enhanced the oxidation potential of the brine, oxidation reactions were limited due to the absence of oxidation-sensitive minerals. Integrated analyses of fluid chemistry, mineralogical characterization, and kinetic reaction modeling indicated that albite dissolution was the primary process governing rock property alteration. Albite dissolution occurring in pores and throats drives pore structure evolution and interconnects isolated pores, thereby leading to a significant increase in the total and connected porosity. As a result, an increase in permeability was observed. The brine percolating through the larger pores initiates the albite dissolution, further widens the seepage pathways and enhances the fluid flow. Ultimately, a quantitative relationship between permeability and porosity influenced by geochemical reactions was established. This study highlights the significance of geochemical reactions in compressed air energy storage in aquifer and provides essential theoretical insights for future numerical simulations and commercial exploitation.
储层流动特性对维持含水层压缩气体蓄能的规模和有效性至关重要。虽然CO2注入引起的流动特性的变化受到了关注,但压缩空气注入引起的地球化学反应对流动特性的影响却被忽视了。本研究通过一系列不同反应条件下的对照实验,揭示了地球化学反应的孔隙尺度机制对孔隙结构和流动特性的影响。虽然空气注入提高了卤水的氧化电位,但由于缺乏氧化敏感矿物,氧化反应受到限制。流体化学、矿物学表征和动力学模拟综合分析表明,钠长石溶蚀是控制岩石蚀变的主要过程。孔喉中钠长石溶蚀作用驱动孔隙结构演化,使孤立孔隙相互连通,使总孔隙度和连通孔隙度显著增加。结果,观察到渗透率的增加。盐水通过较大孔隙渗透,引起钠长石溶蚀,进一步拓宽了渗透通道,增强了流体流动。最后,建立了受地球化学反应影响的渗透率和孔隙度的定量关系。该研究突出了地球化学反应在含水层压缩空气储能中的重要性,为未来的数值模拟和商业开发提供了重要的理论见解。

Flow in fractured porous media is associated with high uncertainty, particularly regarding fracture properties and their overall configuration within the domain. This is especially pronounced for disconnected fractures of smaller yet comparable size to the domain. Consequently, ensemble averages are often used to capture this statistical variability and predict the expected behavior. This leads to enormous computational costs, as flow simulations of single realizations with millions of fractures are extremely expensive; and much more so full Monte Carlo studies involving hundreds of realizations. Alternatively, a recently introduced model aims to directly estimate expected flow rates and pressure fields. The model involves few degrees of freedom, leading to low-cost computations. This is achieved by using integro-differential equations involving non-local kernel functions that encompass the statistical information of fractures. So far this statistical integro-differential fracture model (Sid-FM) considers only ensembles with identical fractures having constant aperture and lengths. In this paper Sid-FM is extended to account for arbitrary fracture aperture profiles and reservoirs with fractures following specified length distributions, which is a crucial step towards applications with realistic fractured reservoirs. In a series of numerical experiments, it is demonstrated that the Sid-FM’s predictions are in excellent agreement with Monte Carlo reference data, which are based on many fracture-resolving simulations. The applicability is demonstrated through statistically one-dimensional cases, laying crucial groundwork for 2D and 3D extensions. Future work will focus on further generalizations and extensions such as transport processes and 2D/3D applications.
裂缝性多孔介质中的流动具有很高的不确定性,特别是在裂缝性质及其在区域内的整体结构方面。对于较小但尺寸与区域相当的未连通裂缝,这一点尤为明显。因此,通常使用集合平均值来捕获这种统计变异性并预测预期的行为。这导致了巨大的计算成本,因为数百万条裂缝的单一实现流模拟非常昂贵;更完整的蒙特卡洛研究涉及数百种实现。另外,最近引入的一种模型旨在直接估计预期的流量和压力场。该模型涉及很少的自由度,导致低成本的计算。这是通过使用包含裂缝统计信息的非局部核函数的积分微分方程来实现的。到目前为止,这种统计积分-微分裂缝模型(Sid-FM)只考虑具有恒定孔径和长度的相同裂缝的整体。本文将Sid-FM扩展到任意裂缝孔径剖面和具有特定长度分布裂缝的储层,这是将其应用于实际裂缝性储层的关键一步。在一系列的数值实验中,Sid-FM的预测与蒙特卡罗参考数据非常吻合,蒙特卡罗参考数据是基于许多裂缝解析模拟得出的。通过统计一维案例证明了该方法的适用性,为二维和三维扩展奠定了重要基础。未来的工作将集中在进一步的概括和扩展,如传输过程和2D/3D应用。

Finding the initial depth-to-water table (DTWT) configuration of a catchment is a critical challenge when simulating the hydrological cycle with integrated models, significantly impacting simulation outcomes. Traditionally, this involves iterative spin-up computations, where the model runs under constant atmospheric settings until steady-state is achieved. These so-called model spin-ups are computationally expensive, often requiring many years of simulated time, particularly when the initial DTWT configuration is far from steady state.
To accelerate the model spin-up process we developed HydroStartML, a machine learning emulator trained on steady-state DTWT configurations across the contiguous United States. HydroStartML predicts, based on available data like conductivity and surface slopes, a DTWT configuration of the respective watershed, which can be used as an initial DTWT.
Our results show that initializing spin-up computations with HydroStartML predictions leads to faster convergence than with other initial configurations like spatially constant DTWTs. The emulator accurately predicts configurations close to steady state, even for terrain configurations not seen in training, and allows especially significant reductions in computational spin-up effort in regions with deep DTWTs.

在使用综合模型模拟水文循环时,寻找集水区的初始深度到地下水位(DTWT)配置是一个关键挑战,对模拟结果有重大影响。传统上,这涉及迭代的自旋上升计算,其中模型在恒定的大气设置下运行,直到达到稳定状态。这些所谓的模型旋转在计算上是昂贵的,通常需要多年的模拟时间,特别是当初始DTWT配置远非稳定状态时。为了加速模型启动过程,我们开发了HydroStartML,这是一种机器学习模拟器,可以在美国各地的稳态DTWT配置上进行训练。根据电导率和地表坡度等可用数据,HydroStartML可以预测相应流域的DTWT配置,这可以用作初始DTWT。我们的结果表明,与其他初始配置(如空间常数dtwt)相比,使用HydroStartML预测初始化自旋向上计算可以更快地收敛。模拟器准确地预测了接近稳态的配置,即使是在训练中没有看到的地形配置,并且在深度dtwt区域可以显著减少计算自旋的工作量。这项工作为混合机器学习和传统模拟的混合方法打开了大门,提高了水文学预测的准确性和效率,以改善水资源管理和理解复杂的环境相互作用。

Evaporation in porous media plays a critical role in systems where optimizing evaporation rates and patterns is vital. Heterogeneous wettability can significantly influence evaporation dynamics by altering capillary forces and liquid connectivity; however, its specific effects on evaporation front morphology, capillary pressure–saturation relationships, and the transition to the falling-rate regime are not well understood. This study addresses this gap by using a modeling framework to simulate evaporation in mixed-wet porous media. The approach combines a three-dimensional pore-network model with a spatially-resolved non-equilibrium continuum model on an identical voxel-based domain. The porous medium is assigned random contact angles ranging from 30°to 150°. Capillary-driven flow and evaporation are simulated, and key metrics such as liquid saturation, capillary pressure, and relative permeability are monitored. Our results show a two-stage drying process. In the initial stage, a highly connected liquid network sustains capillary-driven evaporation with high flux. Over time, liquid clusters become isolated and wet pockets persist, slowing evaporation and inducing a falling-rate regime. Heterogeneous wettability produces a ramified evaporation front, alters capillary pressure dynamics, and affects the evolution of relative permeability. These findings improve our understanding of evaporation kinetics in mixed-wet porous media. They validate the use of a dynamic capillary pressure formulation in continuum models and inform improved modeling of evaporation in environmental and industrial porous materials.
多孔介质中的蒸发在优化蒸发速率和模式至关重要的系统中起着至关重要的作用。非均相润湿性通过改变毛细力和液体连通性显著影响蒸发动力学;然而,其对蒸发锋形态、毛管压力-饱和度关系以及向降速状态过渡的具体影响尚不清楚。本研究通过使用建模框架来模拟混合湿多孔介质中的蒸发,从而解决了这一差距。该方法将三维孔隙网络模型与基于体素的空间分辨非平衡连续体模型相结合。多孔介质的随机接触角范围从30°到150°。模拟了毛细管驱动的流动和蒸发,并监测了液体饱和度、毛细管压力和相对渗透率等关键指标。我们的结果显示了一个两阶段的干燥过程。在初始阶段,高度连通的液体网络维持了毛细管驱动的高通量蒸发。随着时间的推移,液体团簇变得孤立,湿袋持续存在,从而减缓了蒸发,导致了速率的下降。非均相润湿性产生分支化蒸发锋,改变毛管压力动态,影响相对渗透率演化。这些发现提高了我们对混合湿多孔介质蒸发动力学的理解。他们验证了连续模型中动态毛细管压力公式的使用,并改进了环境和工业多孔材料蒸发的建模。

Coastal and hydrologic floods are distinct yet interconnected phenomena, driven by oceanic and terrestrial processes, respectively. Their interaction—known as compound flooding—occurs when storm surge, heavy precipitation, and river flow coincide, significantly amplifying flood impacts in coastal riverine regions. These interactions give rise to a transition zone, where coastal and hydrologic flood processes converge, resulting in complex, prolonged inundation that is challenging to predict using traditional hydrodynamic models. Accurately delineating this zone is essential for improving flood risk assessment and mitigation strategies. In this study, we employ deep learning to quantify the relative contributions of terrestrial hydrologic and coastal flood drivers, enabling spatial delineation of the transition zone within Galveston Bay in Texas. This data-driven approach addresses the limitations of conventional models and supports more effective flood-resilience planning for vulnerable coastal communities. Our results reveal spatial patterns of flood driver dominance, with storm tide influencing coastal zones and river flow playing a greater role inland. The use of SHapley Additive exPlanations (SHAP) enables the delineation of a transition zone where no single driver dominates, underscoring the importance of compound flood modeling in such areas. This framework offers a scalable and interpretable solution for identifying high-risk zones, enhancing the precision of flood risk assessments, and informing targeted mitigation efforts in coastal regions.
沿海洪水和水文洪水是不同但相互关联的现象,分别由海洋和陆地过程驱动。它们的相互作用——被称为复合洪水——发生在风暴潮、强降水和河流流量同时发生的时候,显著地放大了沿海河流地区的洪水影响。这些相互作用产生了一个过渡区,在这里,沿海和水文洪水过程汇合,导致复杂、长期的淹没,这是使用传统水动力模型预测的挑战。准确划定这一区域对于改进洪水风险评估和减灾战略至关重要。在这项研究中,我们使用深度学习来量化陆地水文和沿海洪水驱动因素的相对贡献,从而实现德克萨斯州加尔维斯顿湾过渡带的空间划定。这种数据驱动的方法解决了传统模型的局限性,并为脆弱的沿海社区提供了更有效的洪水恢复规划。研究结果表明,洪涝驱动因素在空间上占主导地位,风暴潮对沿海地区的影响更大,河流对内陆地区的影响更大。SHapley加性解释(SHAP)的使用使得没有单一驱动因素占主导地位的过渡区得以划定,强调了在这些地区进行复合洪水建模的重要性。该框架提供了一个可扩展和可解释的解决方案,用于确定高风险地区,提高洪水风险评估的准确性,并为沿海地区的有针对性的减灾工作提供信息。

This study investigates the effect of submergence ratio on the transport of exogenous particles in streams, targeting particles with density and diameter representative of microplastic and eggs of invasive species, which are of major concern in management of aquatic environments. Transport of two types of surrogate particles, with mean diameters of 1 and 4.8 mm and specific gravities of 1.00 and 1.0025, respectively, was assessed through experiments in a laboratory flume. Submerged obstacles with simplified geometries were mounted on the bed of a flume to represent in-stream obstructions. Image processing techniques, Particle Image Velocimetry (PIV) and Lagrangian Particle Tracking, were used to obtain flow velocity fields and particle trajectories. Angular momentum theorem was used to quantify the emergence of coherent eddies, which increase particle entry and timespans between submerged obstacles. Two indices are introduced: particle entry ratio and timespan of particles, which depend on particle characteristics, submergence ratio, and gap length. The study provides insights into the fundamental physics of particle transport, offering practical implications for aquatic debris and invasive species management, including effective monitoring locations and trap designs.
