Particle-resolved simulation of antidunes in free-surface flows
Christoph Schwarzmeier, Christoph Rettinger, Samuel Kemmler +5
The interaction of supercritical turbulent flows with granular sediment beds is challenging to study both experimentally and numerically; this challenging task has hampered the adv…
Comparison of refilling schemes in the free-surface lattice Boltzmann method
Christoph Schwarzmeier, Ulrich Rüde
Simulating mobile liquid-gas interfaces with the free-surface lattice Boltzmann method (FSLBM) requires frequent re-initialization of fluid flow information in computational cells…
Analysis and comparison of boundary condition variants in the free-surface lattice Boltzmann method
Christoph Schwarzmeier, Ulrich Rüde
The accuracy of the free-surface lattice Boltzmann method (FSLBM) depends significantly on the boundary condition employed at the free interface. Ideally, the chosen boundary condi…
Comparison of free-surface and conservative Allen-Cahn phase-field lattice Boltzmann method
Christoph Schwarzmeier, Markus Holzer, Travis Mitchell +3
This study compares the free-surface lattice Boltzmann method (FSLBM) with the conservative Allen-Cahn phase-field lattice Boltzmann method (PFLBM) in their ability to model two-ph…
waLBerla: A block-structured high-performance framework for multiphysics simulations
Martin Bauer, Sebastian Eibl, Christian Godenschwager +8
Programming current supercomputers efficiently is a challenging task. Multiple levels of parallelism on the core, on the compute node, and between nodes need to be exploited to mak…
Validation and calibration of coupled porous-medium and free-flow problems using pore-scale resolved models
Iryna Rybak, Christoph Schwarzmeier, Elissa Eggenweiler +1
The correct choice of interface conditions and effective parameters for coupled macroscale free-flow and porous-medium models is crucial for a complete mathematical description of…
