Dynamics of Minimal Networks of Limit Cycle Oscillators
Andrea Elizabeth Biju, Sneha Srikanth, Krishna Manoj +2
The framework of mutually coupled oscillators on a network has served as a convenient tool for investigating the impact of various parameters on the dynamics of real-world systems.…
Spatiotemporal Patterns Corresponding to Phase Synchronization and Generalized Synchronization States of Thermoacoustic Instability
Samadhan A. Pawar, P. R. Midhun, K. V. Reeja +3
Thermoacoustic instability in turbulent combustion systems emerges from the complex interplay among the flame, flow, and acoustic subsystems. While the onset of thermoacoustic inst…
Rijke tube: A nonlinear oscillator
Krishna Manoj, Samadhan A. Pawar, Jürgen Kurths +1
Dynamical systems theory has emerged as an interdisciplinary area of research to characterize the complex dynamical transitions in real-world systems. Various nonlinear dynamical p…
Self-coupling: An Effective Method to Mitigate Thermoacoustic Instability
Sneha Srikanth, Ankit Sahay, Samadhan A. Pawar +2
The presence of undesirable large-amplitude self-sustained oscillations in combustors resulting from thermoacoustic instability can lead to performance loss and structural damage t…
Mitigation of limit cycle oscillations in a turbulent thermoacoustic system via delayed acoustic self-feedback
Ankit Sahay, Abhishek Kushwaha, Samadhan A. Pawar +3
We report the occurrence of amplitude death (AD) of limit cycle oscillations in a bluff body stabilized turbulent combustor through delayed acoustic self-feedback. Such feedback co…
Coupled interaction between acoustics and unsteady flame dynamics during the transition to thermoacoustic instability in a multi-element rocket combustor
Praveen Kasthuri, Samadhan A. Pawar, Rohan Gejji +2
Rocket engine combustors are prone to transverse instabilities that are characterized by large amplitude high frequency oscillations in the acoustic pressure and the heat release r…
Dynamical States and Bifurcations in Coupled Thermoacoustic Oscillators
Sneha Srikanth, Samadhan A. Pawar, Krishna Manoj +1
The emergence of rich dynamical phenomena in coupled self-sustained oscillators, primarily synchronization and amplitude death, has attracted considerable interest in several field…
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…
Dynamics of coupled thermoacoustic oscillators under asymmetric forcing: Experiments and theoretical modeling
Ankit Sahay, Amitesh Roy, Samadhan A. Pawar +1
Quenching of limit cycle oscillations (LCO), either through mutual coupling or external forcing, has attracted wide attention in several fields of science and engineering. However,…
Strange nonchaos in self-excited singing flames
D. Premraj, Samadhan A. Pawar, Lipika Kabiraj +1
We report the first experimental evidence of strange nonchaotic attractor (SNA) in the natural dynamics of a self-excited laboratory-scale system. In the previous experimental stud…
