A new numerical mesoscopic scale one-domain approach solver for free fluid/porous medium interaction
Costanza Arico, Rainer Helmig, Daniele Puleo +1
A new numerical continuum \textit{one-domain} approach (ODA) solver is presented for the simulation of the transfer processes between a free fluid and a porous medium. The solver i…
A DuMux Framework for Data-Driven Multi-Scale Parametrizations
Edward Coltman, Martin Schneider, Rainer Helmig
Presented in this work is a framework for the data-driven determination of multi-scale porous media parametrizations. Simulations of flow and transport in a porous medium at the RE…
Flux-mortar mixed finite element methods with multipoint flux approximation
Wietse M. Boon, Dennis Gläser, Rainer Helmig +1
The flux-mortar mixed finite element method was recently developed for a general class of domain decomposition saddle point problems on non-matching grids. In this work we develop…
Modeling of two phase flow in a hydrophobic porous medium interacting with a hydrophilic structure
Cynthia Michalkowski, Kilian Weishaupt, Veronika Schleper +1
Fluid flow through layered materials with different wetting behavior is observed in a wide range of applications in biological, environmental and technical systems. Therefore, it i…
Two-phase flow dynamics at the interface between GDL and gas distributor channel using a pore-network model
Cynthia Michalkowski, Maziar Veyskarami, Carina Bringedal +2
For improved operating conditions of a polymer electrolyte membrane (PEM) fuel cell, a sophisticated water management is crucial. Therefore, it is necessary to understand the trans…
Coupling staggered-grid and vertex-centered finite-volume methods for coupled porous-medium free-flow problems
Martin Schneider, Dennis Gläser, Kilian Weishaupt +3
In this work, a new discretization approach for coupled free and porous-medium flows is introduced, which uses a finite volume staggered-grid method for the discretization of the N…
