A numerical study of premixed flames Darrieus-Landau instability
The complete equations of premixed flames are solved numerically, in the isobaric approximation and with a simplified chemical kinetics. A momentum-pressure formulation is proposed for solving non-constant density flows. The growth rates of the Darrieus-Landau instability are measured and compared to the linear theory. Large amplitude curved flames are obtained, as well as flames submitted to a shear flow.
