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…
