“…Figure c clearly shows that Δ S w is significantly smaller for Ca < Ca c (Δ S w ≤ 0.08) than for Ca > Ca c . Odier et al () performed flow rate‐controlled imbibition experiments in microfluidics and showed that the increased oil saturation after breakthrough is Δ S w ≤ 0.075 in capillary regime (supporting information Figure S8), which is consistent with our results shown in Figure c. From the water‐flooding experiments in water‐wet sandstone, Dullien et al () reported that at capillary imbibition, there is no more oil production after water breakthrough, supporting our results in Figure g.…”

“…In capillary imbibition, studies on pore-scale events, including Haines jump (Haines, 1930), corner flow (Dong & Chatzis, 1995), and snap off (Roof, 1970), have shown that the pore-scale mechanisms not only impact the displacement patterns and efficiency (Chen, Guo, et al, 2018;Hu et al, 2018;Odier et al, 2017) but also contribute to the macroscopic hydraulic properties at the Darcy scale (Niessner et al, 2011). For capillary-viscous regime in imbibition, these local displacement events would be suppressed as viscous forces increasingly dominate the displacement processes (Odier et al, 2017;Zhao et al, 2016). Therefore, identification of the transition is fundamental to the description of forced imbibition.…”

“…Such transition from capillary to capillary‐viscous regimes occurs when the distance from injection wells decreases during water flooding in EOR (Arshadi et al, ; Rücker et al, ) and further identifies different pore‐scale mechanisms of fluid‐fluid interface advancements (Krevor et al, ). In capillary imbibition, studies on pore‐scale events, including Haines jump (Haines, ), corner flow (Dong & Chatzis, ), and snap off (Roof, ), have shown that the pore‐scale mechanisms not only impact the displacement patterns and efficiency (Chen, Guo, et al, ; Hu et al, ; Odier et al, ) but also contribute to the macroscopic hydraulic properties at the Darcy scale (Niessner et al, ). For capillary‐viscous regime in imbibition, these local displacement events would be suppressed as viscous forces increasingly dominate the displacement processes (Odier et al, ; Zhao et al, ).…”

Energy Conversion Reveals Regime Transition of Imbibition in a Rough Fracture

As externally imposed flow rate increases during imbibition, viscous force increasingly dominates displacement over capillarity and imbibition shifts from capillary to capillary‐viscous regimes. Previous studies focused on capillary regime, lacking a fundamental understanding of regime transition. Here we study the imbibition transition via flow rate‐controlled experiments in a rough fracture. By analyzing energy balance in multiphase flow system, we find a fundamental link between regime transition and energy conversion. In capillary regime, surface energy is partially transformed into external work and an amount of 51−58% is dissipated via local rapid, irreversible events; while in capillary‐viscous regime, surface energy together with external work is transformed into kinetic and dissipated energies. This transition, corresponding to critical capillary number, is evidenced by quantitative analysis of invasion morphologies. Our work bridges the gap between energy conversion/dissipation and multiphase flow and has important implications for identifying imbibition regimes in enhanced oil recovery and geological CO2 sequestration.

“…While the gap-averaged two-dimensional approach has been very successful and insightful in describing important nonlinear features of the hydrodynamics of multiphase flows [41,43,[100][101][102][103][104][105][106], it has some limitations. In particular, it cannot resolve the formation of fluid wedges at corners for strongly wetting systems [107][108][109][110][111][112], which exert an important control on the hydraulic continuity of the liquid phase [113,114] and therefore on evaporation rates [115]. Our model can be extended to three dimensions, where the hydrodynamics in the bulk fluid are described by the Navier-Stokes equations.…”

The combination of high-resolution visualization techniques and pore-scale flow modeling is a powerful tool used to understand multiphase flow mechanisms in porous media and their impact on reservoir-scale processes. One of the main open challenges in pore-scale modeling is the direct simulation of flows involving multicomponent mixtures with complex phase behavior. Reservoir fluid mixtures are often described through cubic equations of state, which makes diffuse-interface, or phase-field, theories particularly appealing as a modeling framework. What is still unclear is whether equation-of-state-driven diffuse-interface models can adequately describe processes where surface tension and wetting phenomena play important roles. Here we present a diffuse-interface model of single-component two-phase flow (a van der Waals fluid) in a porous medium under different wetting conditions. We propose a simplified Darcy-Korteweg model that is appropriate to describe flow in a Hele-Shaw cell or a micromodel, with a gap-averaged velocity. We study the ability of the diffuse-interface model to capture capillary pressure and the dynamics of vaporization-condensation fronts and show that the model reproduces pressure fluctuations that emerge from abrupt interface displacements (Haines jumps) and from the breakup of wetting films.

In this review article, we discuss the latest advances and future perspectives of microfluidics for micro/ nanoscale catalyst particle synthesis and analysis. In the first section, we present an overview of the different methods to synthesize catalysts making use of microfluidics and in the second section, we critically review catalyst particle characterization using microfluidics. The strengths and challenges of these approaches are highlighted with various showcases selected from the recent literature. In the third section, we give our opinion on the future perspectives of the combination of catalytic nanostructures and microfluidics. We anticipate that in the synthesis and analysis of individual catalyst particles, generation of higher throughput and better understanding of transport inside individual porous catalyst particles are some of the most important benefits of microfluidics for catalyst research. SynthesisThis section focuses on the most recent approaches within the last 8 years. For a more extensive overview of the synthesis of nanostructures focused on the processes taking place inside the microfluidic systems, 5 the final application 4 or the microfluidic technology used 6,7 we refer the reader to other review articles. Metal nanoparticlesMetal nanoparticles exhibit very interesting catalytic, optical, chemical, electromagnetic and magnetic properties, all of them depending to a large degree on their size and composition. Regarding catalysis, a decrease of the NP size leads to a surface-area increase per mass, providing more active sites. Also, the surface structure is of vital importance for the NP selectivity: the presence of steps, edges or terraces in the atomic surface can influence the reaction pathways to Lab Chip, 2019, 19, 3575-3601 | 3575 This journal is
