A novel numerical scheme for reactive flows at low Mach numbers Original Research Article

For the simulation of low Mach number reactive flows with significant density changes a novel numerical scheme is proposed which contains modified lattice BGK model in combination with the conventional convective-diffusion solvers for equations of temperature and species. Together with boundary-fitting formulation and local 2nd order grid refinement (embedded grids) the scheme enables the accurate consideration of low Mach number combustion in complex geometry in the wide range of Reynolds and Damköler numbers on the simplest Cartesian grids.
