The role of disordered dynamics on the nature of transition in a turbulent reactive flow system
Sivakumar Sudarsanan, Induja Pavithran, R. I Sujith
The transition from a chaotic to a periodic oscillatory state can be smooth or abrupt in real-world turbulent systems. Although there have been several mathematical studies, the oc…
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…
Strange Nonchaotic Attractor in an Unforced Turbulent Reactive Flow System
Beeraiah Thonti, Shruti Tandon, Premraj Durairaj +1
We discover strange nonchaotic attractor (SNA) through experiments in an unforced system comprising turbulent reactive flow. While models suggest SNAs are common in dynamical syste…
Early warnings are too late when parameters change rapidly
Rohit Radhakrishnan, Induja Pavithran, Valerie Livina +2
Early warning signals (EWSs) forewarn a sudden transition (or tipping) from a desirable state to an undesirable state. However, we observe that EWSs detect an impending tipping pas…
Identifying feedback directions in the mechanisms driving self-sustained thermoacoustic instability in a single-element rocket combustor
Somnath De, Praveen Kasthuri, Matthew E. Harvazinski +3
The occurrence of high frequency (>1000 Hz) thermoacoustic instability (TAI) sustained by mutual feedback among the acoustic field, heat release rate oscillations, and hydrodynamic…
Canard explosions in turbulent thermo-fluid systems
Ramesh S. Bhavi, Sivakumar Sudarsanan, Manikandan Raghunathan +2
A sudden transition to a state of high amplitude limit cycle oscillations is catastrophic in a thermo-fluid system. Conventionally, upon varying the control parameter, a sudden tra…
