Although this issue has garnered considerable interest and has been the subject of many numerical analyses, experimental studies remain limited. We present the first experimental investigation of CO<sub>2</sub> diffusive leakage through microfractures in a generalized microfluidic system that represents the key features of the system under realistic CO<sub>2</sub> sequestration conditions. Our findings reveal two-stage depletion kinetics of trapped CO<sub>2</sub> in porous media, driven by dissolution and diffusion through fractures. The first stage is characterized by the rapid dissolution of CO<sub>2</sub> into nearby brine, while the second stage exhibits a steady leakage rate as CO<sub>2</sub> diffuses through the fractures into a water sink, driven by the solubility limit, assuming stable microfracture structures and negligible advection. Between these two stages, there is a transition period during which CO<sub>2</sub> saturation remains stable. Two key parameters are proposed to quantify the diffusive leakage process: the transition time and the steady-state leakage rate.

This work developed pore-scale lattice Boltzmann (LB) modeling to simulate water-air multiphase flow and solute transport in the aqueous phase, which unraveled the role of the water saturation and Peclet (Pe) number on solute dispersivity in unsaturated three-dimensional porous media. The Pe number and water saturation influenced the solute concentration profile along the longitudinal direction in a coupled manner. Under a low Pe number, the solute concentration profile approximately followed the classic Gaussian distribution regardless of the water saturation. Under a high Pe number, the solute concentration profile became skewed and the role of the water saturation was noticeable. Under a moderate water saturation, a significant portion of the solute particles were trapped at the trailing edge, leading to the non-Fickian transport behavior. In contrast, with a high water saturation, the enhanced water connectivity in the pore space mitigated the trapping of solute particles at the trailing edge, leading to the classic Fickian dispersion. This study also showed the non-monotonic dependence of longitudinal dispersivity on the water saturation, which was caused by a competing process between pore water connectivity and flow field heterogeneity. The pore-scale simulation confirmed that the dispersivity is not a constant but depends on the Pe number nonlinearly. Therefore, there is a complicated coupling between the dispersivity, water saturation, and Pe number for multiphase flows in porous media. This study developed a six-parameter empirical model to account for the role of the water saturation and Pe number on the longitudinal dispersivity in unsaturated flows. This empirical model can be used to predict the solute dispersion coefficient in unsaturated porous media, which is critical to large-scale contaminant transport modeling.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"199 ","pages":"Article 104957"},"PeriodicalIF":4.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we explore flow dynamics around a vertical cylinder (simulating vegetation) over a coarse granular bed using stereo particle image velocimetry (SPIV) with refractive index-matched (RIM) fluid, integrated with Large Eddy Simulations (LES). Our combined approach reveals an important phenomenon: while large obstacles like vegetation stalks create localized pressure gradients, bed roughness elements generate frequent pressure fluctuations across the entire streambed. Although previous studies have focused primarily on large-obstacle effects, our findings show that grain-scale pressure variations generate stronger local gradients (up to ±250 mmH₂O/m) than those from large obstacles (±50 mmH₂O/m), and their widespread occurrence throughout the bed surface may collectively have substantial effects on hyporheic exchange. By quantifying pressure fields at both large and small scales, we demonstrate that bed roughness elements create persistent pressure gradients that, due to their widespread occurrence, may significantly influence surface-subsurface water interactions.

Here, a long-range adsorptive fluid-solid interaction force is developed in the mesoscopic multiphase lattice Boltzmann model (LBM) framework to model the macroscopic processes of capillarity and adsorption. The pressure tensors of capillary and film water derived based on mechanical equilibrium and the results of numerical simulations combine to show that the adsorptive suction is much higher than the capillary suction, not following the classical relationship. We attribute this inequality to the different adsorptive interaction potentials incorporated in the capillary and film water pressures, due to the fluid density profiles varying differently with the separation distance from solid surface, and, from the perspective of thermodynamic equilibrium, the deviation of film water and capillary water densities from free water density. The film thickness almost does not change for the given radii of meniscus curvature in simple geometries (i.e., slits and corners).
