Multiphysics flow simulations using D3Q19 lattice Boltzmann methods based on central moments
Alessandro De Rosis, Christophe Coreixas
In a recent work [A. De Rosis, R. Huang, and C. Coreixas, "Universal formulation of central-moments-based lattice Boltzmann method with external forcing for the simulation of multi…
Compressible lattice Boltzmann methods with adaptive velocity stencils: An interpolation-free formulation
C. Coreixas, J. Latt
Adaptive lattice Boltzmann methods (LBMs) are based on velocity discretizations that self-adjust to local macroscopic conditions such as velocity and temperature. While this featur…
Linear stability of athermal regularized lattice Boltzmann methods
Gauthier Wissocq, Christophe Coreixas, Jean-François Boussuge
The present work is dedicated to a better understanding of the stability properties of regularized lattice Boltzmann (LB) schemes. To this extent, linear stability analyses of two-…
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…
