Periodic modulation of the space-filling nature of the turbulent flame leads to spiky heat release oscillations
Sivakumar Sudarsanan, Manikandan Raghunathan, Shwetha Viswesh +1
Spiky oscillations are characterized by slow-fast dynamics and are observed in excitable media such as neuronal membranes and cardiac cells. In a turbulent reactive flow system, we…

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…
