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…
twoPhaseInterTrackFoam: an OpenFOAM module for Arbitrary Lagrangian/Eulerian Interface Tracking with Surfactants and Subgrid-Scale Modeling
Moritz Schwarzmeier, Suraj Raju, Željko TukoviÄ +3
We provide an implementation of the unstructured Finite-Volume Arbitrary Lagrangian / Eulerian (ALE) Interface-Tracking method for simulating incompressible, immiscible two-phase f…
Beyond the Cassie-Baxter Model: New Insights for Predicting Imbibition in Complex Systems
Mathis Fricke, Lisanne Gossel, Joel De Coninck
We revisit the classical problem of liquid imbibition in a single pore with spatially varying wettability. Starting from the Lucas-Washburn equation, we derive analytical solutions…
Numerical wetting benchmarks -- advancing the plicRDF-isoAdvector unstructured Volume-of-Fluid (VOF) method
Muhammad Hassan Asghar, Mathis Fricke, Dieter Bothe +1
The numerical simulation of wetting and dewetting of geometrically complex surfaces benefits from unstructured numerical methods because they discretize the domain with second-orde…
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…
Experimental study of dynamic wetting behavior through curved microchannels with automated image analysis
Huijie Zhang, Anja Lippert, Ronny Leonhardt +4
Preventing fluid penetration poses a challenging reliability concern in the context of power electronics, which is usually caused by unforeseen microfractures along the sealing joi…
