Lattice-Boltzmann model for low-Mach reactive flows

International audienceRecent advancements on Lattice-Boltzmann methods for com-bustion modeling will be presented. After a brief review of existing models, we will present a simplified model for reactive flows valid for moderate velocities (Ma <0.3). The approach couples a compressible Lattice-Boltzmann solver based on standard (nearest-neighbor) lattices, and a finite difference solver for the energy and species conservation. The classical multi-component thermo-dynamic closure is recovered, including component-specific variable Cp and transport properties, as well as non-unity Prandtl number. Validations are then presented including 1-D freely propagating flame, counterflow diffusion flame, and Darrieus-Landau instabilit
