Coupling fully resolved light particles with the Lattice Boltzmann method on adaptively refined grids
Lukas Werner, Christoph Rettinger, Ulrich Rüde
The simulation of geometrically resolved rigid particles in a fluid relies on coupling algorithms to transfer momentum both ways between the particles and the fluid. In this articl…
Textbook efficiency: massively parallel matrix-free multigrid for the Stokes system
Nils Kohl, Ulrich Rüde
We employ textbook multigrid efficiency (TME), as introduced by Achi Brandt, to construct an asymptotically optimal monolithic multigrid solver for the Stokes system. The geometric…
An efficient four-way coupled lattice Boltzmann - discrete element method for fully resolved simulations of particle-laden flows
Christoph Rettinger, Ulrich Rüde
A four-way coupling scheme for the direct numerical simulation of particle-laden flows is developed and analyzed. It employs a novel adaptive multi-relaxation time lattice Boltzman…
A Coupled Lattice Boltzmann Method and Discrete Element Method for Discrete Particle Simulations of Particulate Flows
Christoph Rettinger, Ulrich Rüde
Discrete particle simulations are widely used to study large-scale particulate flows in complex geometries where particle-particle and particle-fluid interactions require an adequa…
