Many complex systems undergo critical transitions. A thermoacoustic system is one such
system which exhibits a catastrophic transition to a state of oscillatory instability known as …

This study focuses on characterizing the bifurcation scenario and the underlying synchrony
behavior in a nonlinear aeroelastic system under deterministic as well as stochastic inflow …

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 …

We present a phenomenological reduced-order model to capture the transition to
thermoacoustic instability in turbulent combustors. Based on the synchronization framework …

Chaotic motion in a fluttering wind turbine blade is investigated by the development of an
efficient analytical predictive model that is then used to suppress the phenomenon. Flutter is …

The present study aims to investigate the synchronization characteristics of a pitch–plunge
aeroelastic system subjected to coupled structural free-play and dynamic stall-induced …

We perform laboratory-scale experiments in a swirl combustor by reducing the equivalence
ratio for two cases involving slightly different inlet air flow rates. Reduction in equivalence …

We numerically study the dynamic behavior and driving region of spray combustion
instability in a backward-facing step combustor using analytical methodologies based on …

The multi-agent system has been a hot topic in the past few decades owing to its lower cost,
higher robustness, and higher flexibility. As a particular multi-agent system, the multiple rigid …

Self-excited thermoacoustic oscillations are undesirable in most combustion systems due to
their negative influence on combustion efficiency and structural vibration. Nonlinear …
