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…
Two-phase pore-network model for evaporation-driven salt precipitation -- representation and analysis of pore-scale processes
Theresa Schollenberger, Christian Rohde, Rainer Helmig
Evaporation-driven salt precipitation occurs in different contexts and leads to challenges in case of e.g. soil salinization or stress-introducing precipitation in building materia…
Mixed finite element projection methods for the unsteady Stokes equations
Costanza Aricò, Rainer Helmig, Ivan Yotov
We develop (div)-conforming mixed finite element methods for the unsteady Stokes equations modeling single-phase incompressible fluid flow. A projection method in the framework…
A mortar method for the coupled Stokes-Darcy problem using the MAC scheme for Stokes and mixed finite elements for Darcy
Wietse M. Boon, Dennis Gläser, Rainer Helmig +2
A discretization method with non-matching grids is proposed for the coupled Stokes-Darcy problem that uses a mortar variable at the interface to couple the marker and cell (MAC) me…
