Multi-scale three-domain approach for coupling free flow and flow in porous media including droplet-related interface processes
Sina Ackermann, Carina Bringedal, Rainer Helmig
Drops on a free-flow/porous-medium-flow interface have a strong influence on the exchange of mass, momentum and energy between the two macroscopic flow regimes. Modeling droplet-re…
