Numerical analysis of the Navier-Stokes/Darcy coupling
journal contribution
posted on 2015-09-11, 14:35 authored by Lori Badea, Marco DiscacciatiMarco Discacciati, Alfio QuarteroniWe consider a differential system based on the coupling of the Navier–
Stokes and Darcy equations for modeling the interaction between surface and
porous-media flows. We formulate the problem as an interface equation, we analyze
the associated (nonlinear) Steklov–Poincaré operators, and we prove its well-posedness.
We propose and analyze iterative methods to solve a conforming finite element
approximation of the coupled problem.
