Abstract
The complete equations of premixed flames are solved numerically, in t he isobaric approximation and with a simplified chemical kinetics. A m omentum-pressure formulation is proposed for solving non-constant dens ity flows. The growth rates of the Darrieus-Landau instability are mea sured and compared to the linear theory. Large amplitude curved flames are obtained, as well as flames submitted to a shear flow.
