Abstract
Rough a global coarse problem. Although these techniques are usually
employed for problems in which the fine-scale processes are described
by Darcy's law, they can also be applied to pore-scale simulations
and used as a mathematical framework for hybrid methods that couples
a Darcy and pore scales. In this work, we consider a pore-scale description
of fine-scale processes. The Navier-Stokes equations are numerically
solved in the pore geometry to compute the velocity field and obtain
generalized permeabilities. In the case of two-phase flow, the dynamics
of the phase interface is described by the volume of fluid method
with the continuum surface force model. The MsFV method is employed
to construct an algorithm that couples a Darcy macro-scale description
with a pore-scale description at the fine scale. The hybrid simulations
results presented are in good agreement with the fine-scale reference
solutions. As the reconstruction of the fine-scale details can be
done adaptively, the presented method offers a flexible framework
for hybrid modeling.
