Abstract
The process of combustion of a premixed lean methane/air mixture in the model low-emission combustor is studied. Several known mechanisms of the self-oscillation generation and the flame flashback are analyzed. Numerical LES and SAS calculations of several combustors of typical configurations and regime parameters are presented. Some means of suppressing the flame flashback are proposed and analyzed.
