In this work, the dynamics of the pressure oscillations and flame behaviors in a premixed
swirl-stabilized combustor were experimentally investigated. As equivalence ratio Φ varied …

The phenomena of combustion instabilities beyond limit cycles caused by the nonlinear
interaction of various instability modes have recently received much attention. This paper …
