Abstract: A combustor assembly employs an ejector assembly having an array of swirlers to influence the flow field, reduce unburned fuel emissions, enhance flame stabilization and reduce noise within a combustion chamber. The swirlers are located downstream of a premixing section and are designed to correct bias of fuel-air mixture residence times in the combustion chamber. The ejector assembly may be tuned to any particular configuration by varying the swirl number in order to produce recirculation zones that ensure out of phase nature of the heat release within the combustion chamber.
