Open AccessUpscaling and Effective Behavior for Two-Phase Porous-Medium Flow Using a Diffuse Interface Model
We investigate two-phase flow in porous media and derive a two-scale model, which incorporates pore-scale phase distribution and surface tension into the effective behavior at the larger Darcy scale. The free-...

Open AccessVisual Ensemble Analysis of Fluid Flow in Porous Media Across Simulation Codes and Experiment
We study the question of how visual analysis can support the comparison of spatio-temporal ensemble data of liquid and gas flow in porous media. To this end, we focus on a case study, in which nine different r...

Open AccessA surrogate-assisted uncertainty-aware Bayesian validation framework and its application to coupling free flow and porous-medium flow
Existing model validation studies in geoscience often disregard or partly account for uncertainties in observations, model choices, and input parameters. In this work, we develop a statistical framework that i...

Open AccessRelating Darcy-Scale Chemical Reaction Order to Pore-Scale Spatial Heterogeneity
Due to spatial scaling effects, there is a discrepancy in mineral dissolution rates measured at different spatial scales. Many reasons for this spatial scaling effect can be given. We investigate one such reas...

Open AccessComparison study of phase-field and level-set method for three-phase systems including two minerals
We investigate reactive flow and transport in evolving porous media. Solute species that are transported within the fluid phase are taking part in mineral precipitation and dissolution reactions for two compet...
