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…
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…
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…
