Impact of collision models on the physical properties and the stability of lattice Boltzmann methods
C. Coreixas, G. Wissocq, B. Chopard +1
The lattice Boltzmann method (LBM) is known to suffer from stability issues when the collision model relies on the BGK approximation, especially in the zero viscosity limit and for…
Efficient supersonic flows through high-order guided equilibrium with lattice Boltzmann
Jonas Latt, Christophe Coreixas, Joel Beny +1
A double-distribution-function based lattice Boltzmann method (DDF-LBM) is proposed for the simulation of polyatomic gases in the supersonic regime. The model relies on an extended…
Comprehensive comparison of collision models in the lattice Boltzmann framework: Theoretical investigations
C. Coreixas, B. Chopard, J. Latt
Over the last decades, several types of collision models have been proposed to extend the validity domain of the lattice Boltzmann method (LBM), each of them being introduced in it…
Efficient LBM on GPUs for dense moving objects using immersed boundary condition
Joel Beny, Jonas Latt
There exists an increasing interest for using immersed boundary methods (IBMs) (Peskin 2000) to model moving objects in computational fluid dynamics. Indeed, this approach is parti…
Bridging the computational gap between mesoscopic and continuum modeling of red blood cells for fully resolved blood flow
Christos Kotsalos, Jonas Latt, Bastien Chopard
We present a computational framework for the simulation of blood flow with fully resolved red blood cells (RBCs) using a modular approach that consists of a lattice Boltzmann solve…
Spatial Coupling of a Lattice Boltzmann fluid model with a Finite Difference Navier-Stokes solver
Jonas Latt, Bastien Chopard, Paul Albuquerque
In multiscale, multi-physics applications, there is an increasing need for coupling numerical solvers that are each applied to a different part of the problem. Here we consider the…
