Experimental investigation on the susceptibility of minimal networks to a change in topology and number of oscillators
Krishna Manoj, Samadhan A. Pawar, R. I. Sujith
Understanding the global dynamical behaviour of a network of coupled oscillators has been a topic of immense research in many fields of science and engineering. Various factors gov…
Critical region in the spatiotemporal dynamics of a turbulent thermoacoustic system and smart passive control
Amitesh Roy, C P Premchand, Manikandan Raghunathan +3
We develop a passive control strategy for suppressing thermoacoustic instability in a bluff-body stabilized premixed turbulent combustor. When the equivalence ratio is varied, ther…
Fractal dimension of premixed flames in multifractal turbulence
Amitesh Roy, R I Sujith
In turbulent premixed flames, the fractal dimension of flame iso-surface is argued to be for Damköhler's large-scale limit and for Damkö…
Synchronization framework for modeling transition to thermoacoustic instability in laminar combustors
Yue Weng, Vishnu R. Unni, R. I. Sujith +1
We, herein, present a new model based on the framework of synchronization to describe a thermoacoustic system and capture the multiple bifurcations that such a system undergoes. In…
Universality in spectral condensation
Induja Pavithran, Vishnu R. Unni, Alan John Varghese +6
Self-organization is the spontaneous formation of spatial, temporal, or spatiotemporal patterns in complex systems far from equilibrium. During such self-organization, energy distr…
Flame dynamics during intermittency and secondary bifurcation to longitudinal thermoacoustic instability in a swirl-stabilized annular combustor
Amitesh Roy, Samarjeet Singh, Asalatha Nair +2
In this experimental study on a laboratory-scale turbulent annular combustor with sixteen swirl-stabilized burners, we study the flame-flame and flame-acoustic interactions during…
