Effects of swirl numbers on the unsteady characteristics of pilot flame in a triple-swirler staged combustor

This paper studies the effects of the inner and outer pilot swirlers on the flame structures and thermo-acoustic instabilities in the triple-swirler staged combustors under various inner and outer pilot swirl numbers. We obtain energetic modes in the combustor's velocity and the OH radical mass...
