Improvement of fully-implicit two-phase pore-network models by employing generalized flux functions with additional throat variables
Martin Schneider, Hanchuan Wu, Maziar Veyskarami +2
In fully-implicit two-phase pore-network models, developing a well-converged scheme remains a major challenge, primarily due to the discontinuities in the phase conductivities. Thi…
Data-Driven Closure Parametrizations with Metrics: Dispersive Transport
Edward Coltman, Martin Schneider, Rainer Helmig
This work presents a data-driven framework for multi-scale parametrization of velocity-dependent dispersive transport in porous media. Pore-scale flow and transport simulations are…
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…
Stable and locally mass- and momentum-conservative control-volume finite-element schemes for the Stokes problem
Martin Schneider, Timo Koch
We introduce new control-volume finite-element discretization schemes suitable for solving the Stokes problem. Within a common framework, we present different approaches for constr…
