Metamorphosis of transition to periodic oscillations in a turbulent reactive flow system
Beeraiah Thonti, Sivakumar Sudarsanan, Ramesh S. Bhavi +3
The emergence of periodic oscillations is observed in various complex systems in nature and engineering. Thermoacoustic oscillations in systems comprising turbulent reactive flow e…

Control of growth of local heat release rate fluctuations to suppress thermoacoustic instability
M. Raghunathan, N. B. George, V. R Unni +3
This experimental study investigates the dynamical transition from stable operation to thermoacoustic instability in a turbulent bluff-body stabilized dump combustor. We conduct ex…

Critical region in the spatiotemporal dynamics of a turbulent thermoacoustic system and smart passive control
Amitesh Roy, C P Premchand, Manikandan Raghunathan +3
We develop a passive control strategy for suppressing thermoacoustic instability in a bluff-body stabilized premixed turbulent combustor. When the equivalence ratio is varied, ther…
