从这个角度来看，我们简要概述了可变形颗粒介质多相流领域的知识状况和最新进展。我们通过许多例子表明，孔隙尺度上的粘性力、毛细管力和摩擦力之间的相互作用决定了流体侵入的模式。我们特别关注润湿性对颗粒填充变形和破坏形态的核心作用。除了作为引起壮观图案形成的过程的内在兴趣之外，颗粒介质中的这些耦合现象还可以控制大陆尺度的通量，例如从海底排放的甲烷以及地震和山体滑坡等地质灾害。我们通过指出基本知识差距和令人兴奋的研究途径来总结这一观点。
In this perspective we provide a brief overview of the state of knowledge and recent progress in the area of multiphase flow through deformable granular media. We show, with many examples, that the interplay between viscous, capillary, and frictional forces at the pore scale determines the mode of fluid invasion. We pay particular attention to the central role of wettability on the morphology of granular-pack deformation and failure. Beyond their intrinsic interest as processes that give rise to spectacular pattern formation, these coupled phenomena in granular media can control continental-scale fluxes like methane venting from the seafloor and geohazards like earthquakes and landslides. We conclude this perspective by pointing to fundamental knowledge gaps and exciting avenues of research.
