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 …

Dynamical systems theory has emerged as an interdisciplinary area of research to
characterize the complex dynamical transitions in real-world systems. Various nonlinear …

Nonlinear self-excited thermoacoustic oscillations appear in systems involving confined
combustion in the form of coupled acoustic pressure oscillations and unsteady heat release …

Thermoacoustic instability, also known as combustion instability, continues to be a problem
in the development of modern gas turbine combustors and rocket engines. Such instability is …

Complex thermoacoustic oscillations are observed experimentally in a simple laboratory
combustor that burns lean premixed fuel-air mixture, as a result of nonlinear interaction …

Thermoacoustic instability is the result of a positive coupling between the acoustic field in
the duct and the heat release rate fluctuations from the flame. Recently, in several turbulent …

Thermoacoustic systems can oscillate self-excitedly, and often non-periodically, owing to
coupling between unsteady heat release and acoustic waves. We study a slot-stabilized two …

In nonlinear dynamics, there are three classic routes to chaos, namely the period-doubling
route, the Ruelle–Takens–Newhouse route and the intermittency route. The first two routes …

In this work, the dynamics of the pressure oscillations and flame behaviors in a premixed
swirl-stabilized combustor were experimentally investigated. As equivalence ratio Φ varied …

Bifurcation analysis is performed on experimental data obtained from a simple setup
comprising ducted laminar premixed conical flames in order to investigate the features of …
