Iryna Rybak: Interface conditions for arbitrary flows in Stokes-Darcy systems
17 december 2021 12:30
Existing coupling conditions for free-flow and porous-medium systems (Stokes-Darcy problem) are applicable only for uni-directional flows which are parallel or perpendicular to the fluid-porous interface.
In this talk, a new set of coupling conditions valid for arbitrary flow directions will be presented. These conditions have been derived using the theory of homogenization and validated numerically against pore-scale resolved models. The advantages of the new conditions over the classical ones will be demonstrated.
