论文摘要
提出了一种开源的多相Darcy-Brinkman方法，以模拟包含无固体区域和多孔矩阵的混合系统中的两相流。该微核模型植根于基本物理和音量平均原理，其中使用一组唯一的部分微分方程来表示在两个区域和尺度中的流动。该模型的症结在于，它渐近地倾向于无固体区域中的Navier-Stokes-Stokes-Stokes-Stokes-Stokes量量，并倾向于多孔区域的多相DARCY方程。与现有的多尺度多相求解器不同，它可以匹配毛细管，相对渗透性和孔隙尺度的重力效应的分析预测。通过其开源实现，杂交互联剂，提出的方法标志着计算流体动力学（CFD）仿真软件包的扩展为多孔多尺度的多阶段系统。使用应用于断裂的多孔矩阵中的两相流量和与多孔沿海屏障的波动相互作用，用应用程序进行了求解器的多功能性。
An open-sourced multiphase Darcy-Brinkman approach is proposed to simulate two-phase flow in hybrid systems containing both solid-free regions and porous matrices. This micro-continuum model is rooted in elementary physics and volume averaging principles, where a unique set of partial differential equations is used to represent flow in both regions and scales. The crux of the proposed model is that it tends asymptotically towards the Navier-Stokes volume-of-fluid approach in solid-free regions and towards the multiphase Darcy equations in porous regions. Unlike existing multiscale multiphase solvers, it can match analytical predictions of capillary, relative permeability, and gravitational effects at both the pore and Darcy scales. Through its open-source implementation, hybridPorousInterFoam, the proposed approach marks the extension of computational fluid dynamics (CFD) simulation packages into porous multiscale, multiphase systems. The versatility of the solver is illustrated using applications to two-phase flow in a fractured porous matrix and wave interaction with a porous coastal barrier.
