Early warning signals for primary and secondary bifurcation to oscillatory instabilities
Rohit Radhakrishnan, Prasana Kumar, Induja Pavithran +1
In several natural and engineering systems, changes in control parameters can trigger bifurcations that lead to sustained or growing periodic oscillations, indicating the onset of…
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…
Emergence of order from chaos through a continuous phase transition in a turbulent reactive flow system
Sivakumar Sudarsanan, Amitesh Roy, Induja Pavithran +2
As the Reynolds number is increased, a laminar fluid flow becomes turbulent, and the range of time and length scales associated with the flow increases. Yet, in a turbulent reactiv…
Explosive synchronization in a turbulent reactive flow system
Amal Joseph, Induja Pavithran, R. I. Sujith
The occurrence of abrupt dynamical transitions in the macroscopic state of a system has received growing attention. We present experimental evidence for abrupt transition via explo…
Frequency shifts during whistling occurs as transition between two phase synchronised limit cycles via a state of intermittency or abruptly
Ramesh S. Bhavi, Induja Pavithran, R. I. Sujith
Self-sustained oscillations arising from the interactions between the hydrodynamic and the acoustic field are disastrous in engineering systems such as segmented solid rocket motor…
Early warnings of tipping in a non-autonomous turbulent reactive flow system: efficacy, reliability, and warning times
Ankan Banerjee, Induja Pavithran, R. I. Sujith
Real-world complex systems such as the climate, ecosystems, stock markets, and combustion engines are prone to dynamical transitions from one state to another, with catastrophic co…
