Lattice Boltzmann model approximated with finite difference expressions
François Dubois, Pierre Lallemand, Christian Obrecht +1
We show that the asymptotic properties of the link-wise artificial compressibility method are not compatible with a correct approximation of fluid properties. We propose to adapt t…
Stability of a bidimensional relative velocity lattice Boltzmann scheme
François Dubois, Tony Février, Benjamin Graille
In this contribution, we study the theoretical and numerical stability of a bidimensional relative velocity lattice Boltzmann scheme. These relative velocity schemes introduce a ve…
On the stability of a relative velocity lattice Boltzmann scheme for compressible Navier-Stokes equations
François Dubois, Tony Fevrier, Benjamin Graille
This paper studies the stability properties of a two dimensional relative velocity scheme for the Navier-Stokes equations. This scheme inspired by the cascaded scheme has the parti…
Third order equivalent equation for the relative velocity lattice Boltzmann schemes with one conservation law
Benjamin Graille, François Dubois, Tony Fevrier
We study the formal precision of the relative velocity lattice Boltzmann schemes. They differ from the d'Humières schemes by their relaxation phase: it occurs for a set of moments…
Finite volumes and mixed Petrov-Galerkin finite elements : the unidimensional problem
François Dubois
For Laplace operator in one space dimension, we propose to formulate the heuristic finite volume method with the help of mixed Petrov-Galerkin finite elements. Weighting functions…
Simulation of strong nonlinear waves with vectorial lattice Boltzmann schemes
François Dubois
We show that an hyperbolic system with a mathematical entropy can be discretized with vectorial lattice Boltzmann schemes with the methodology of kinetic representation of the dual…
Lattice Boltzmann schemes with relative velocities
François Dubois, Tony Fevrier, Benjamin Graille
In this contribution, a new class of lattice Boltzmann schemes is introduced and studied. These schemes are presented in a framework that generalizes the multiple relaxation times…
Isotropy conditions for lattice Boltzmann schemes. Application to D2Q9
Adeline Augier, François Dubois, Benjamin Graille
In this paper, we recall the linear version of the lattice Boltzmann schemes in the framework proposed by d'Humiéres. According to the equivalent equations we introduce a definitio…
