Local Thermal Non-Equilibrium Models in Porous Media: A Comparative Study of Conduction Effects
Anna Mareike Kostelecky, Ivar Stefansson, Carina Bringedal +3
Instantaneous heat transfer between different phases is a common assumption for modeling heat transfer in porous media, known as Local Thermal Equilibrium (LTE). This assumption ma…
Impact of saturation on evaporation-driven density instabilities in porous media: mathematical and numerical analysis
C. Bringedal, S. Kiemle, C. J. van Duijn +1
Evaporation from a porous medium partially saturated with saline water, causes the salinity (salt concentration) to increase near the top of the porous medium as water leaves while…
Upscaling and Effective Behavior for Two-Phase Porous-Medium Flow using a Diffuse Interface Model
Mathis Kelm, Carina Bringedal, Bernd Flemisch
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…
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…
A phase-field approach to model evaporation from porous media: Modeling and upscaling
Tufan Ghosh, Carina Bringedal, Christian Rohde +1
We develop a phase-field model for evaporation from a porous medium by explicitly considering a vapor component together with the liquid and gas phases in the system. The phase-fie…
Evaporation-driven density instabilities in saturated porous media
Carina Bringedal, Theresa Schollenberger, G. J. M. Pieters +2
Soil salinization is a major cause of soil degradation and hampers plant growth. For soils saturated with saline water, the evaporation of water induces accumulation of salt near t…
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…
