DeboRheo v2.0: Improved Robustness for Geometrical VOF Simulations of Viscoelastic Two-Phase Flows
Daulet Izbassarov, Matthias Niethammer, Rahul Subburaj +5
We present DeboRheo v2.0, an unstructured, geometrically unsplit Volume-of-Fluid framework implemented in OpenFOAM for viscoelastic two-phase flows. Version 2.0 improves numerical…
From a three-fluid junction to Young's law: Constitutive and rigid-support limits of wetting
Dieter Bothe
Young's law on a rigid solid and the Neumann balance at a three-fluid junction describe different admissible motions. We connect them through an ordered continuum construction. An…
A consistent treatment of dynamic contact angles in the sharp-interface framework with the generalized Navier boundary condition
Tomas Fullana, Yash Kulkarni, Mathis Fricke +4
In this work, we revisit the Generalized Navier Boundary condition (GNBC) introduced by Qian et al.\ in the sharp interface Volume-of-Fluid context. We replace the singular uncompe…
On the problem of optimal fluid transport in capillaries
Mathis Fricke, Clara Bernklau, Elisabeth Diehl +3
In this note, we revisit the problem of the pressure-driven transport of a meniscus through a narrow cylindrical capillary or pore. This generic process finds many applications in…
Scale-bridging within a complex model hierarchy for investigation of a metal-fueled circular energy economy by use of Bayesian model calibration with model error quantification
Lisanne Gossel, Elisa Corbean, Sören Dübal +7
Metal energy carriers recently gained growing interest in research as a promising storage and transport material for renewable electricity. Within the development of a metal-fueled…
twoPhaseInterTrackFoam: an OpenFOAM module for Arbitrary Lagrangian/Eulerian Interface Tracking with Surfactants and Subgrid-Scale Modeling
Moritz Schwarzmeier, Suraj Raju, Željko Tuković +3
We provide an implementation of the unstructured Finite-Volume Arbitrary Lagrangian / Eulerian (ALE) Interface-Tracking method for simulating incompressible, immiscible two-phase f…
Bridging the scales in capillary rise dynamics with complexity-reduced models
Mathis Fricke, Suraj Raju, El Assad Ouro-Koura +5
Dynamic wetting processes inherently manifest as multiscale phenomena. While the capillary length is typically millimeters, solid-liquid interactions occur at the nanometer scale.…
Imaging and simulation-based analysis of evaporation flows over wetting edges
Suraj Raju, Felix Braig, Mathis Fricke +4
We monitor the evaporation of a volatile liquid (ethanol) from an inkjet-printed liquid film, consisting of a mixture of ethanol and ethylene glycol. Interferometric video imaging…
Analytical and numerical validation of a plate-plate tribometer for measuring wall slip
Muhammad Hassan Asghar, Tomislav Maric, Houssem Ben Gozlen +5
We model the Darmstadt Slip Length Tribometer (DSLT), specially designed to measure viscosity and slip length simultaneously for lubrication gaps in the range of approximately 10 m…
An unstructured geometrical un-split VOF method for viscoelastic two-phase flows
Matthias Niethammer, Muhammad Hassan Asghar, Tomislav Maric +1
Since viscoelastic two-phase flows arise in various industrial and natural processes, developing accurate and efficient software for their detailed numerical simulation is a highly…
Mathematical analysis of modified level-set equations
Dieter Bothe, Mathis Fricke, Kohei Soga
The linear transport equation allows to advect level-set functions to represent moving sharp interfaces in multiphase flows as zero level-sets. A recent development in computationa…
A pragmatic workflow for research software engineering in computational science
Tomislav Marić, Dennis Gläser, Jan-Patrick Lehr +4
University research groups in Computational Science and Engineering (CSE) generally lack dedicated funding and personnel for Research Software Engineering (RSE), which, combined wi…
