Comparison of cell- and vertex-centered finite-volume schemes for flow in fractured porous media
Dennis Gläser, Martin Schneider, Bernd Flemisch +1
Flow in fractured porous media is of high relevance in a variety of geotechnical applications, given the fact that they ubiquitously occur in nature and that they can have a substa…
Flux-mortar mixed finite element methods on non-matching grids
Wietse M. Boon, Dennis Gläser, Rainer Helmig +1
We investigate a mortar technique for mixed finite element approximations of Darcy flow on non-matching grids in which the normal flux is chosen as the coupling variable. It plays…
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…
Model reduction for coupled free flow over porous media: a hybrid dimensional pore network model approach
Kilian Weishaupt, Alexandros Terzis, Ioannis Zarikos +3
Modeling coupled systems of free flow adjacent to a porous medium by means of fully resolved Navier-Stokes equations is limited by the immense computational cost and is thus only f…
A new and consistent well model for one-phase flow in anisotropic porous media using a distributed source model
Timo Koch, Rainer Helmig, Martin Schneider
A new well model for one-phase flow in anisotropic porous media is introduced, where the mass exchange between well and a porous medium is modeled by spatially distributed source t…
Fronts in two-phase porous flow problems: effects of hysteresis and dynamic capillarity
Koondanibha Mitra, Tobias Köppl, Cornelis Johannes van Duijn +2
In this work, we study the behaviour of saturation fronts for two phase flow through a long homogeneous porous column. In particular, the model includes hysteresis and dynamic effe…
