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

Thermoacoustic systems are self-oscillating due to the fact that a constant input (eg, fuel rate
in gas-turbine combustors) yields an asymptotically oscillatory response. This behavior …

This paper proposes an adaptive scheme for the boundary stabilization of thermoacoustic
instability in the Rijke tube system using the backstep** method. The mathematical model …

This study applies the Green's function method to investigate the modal interaction during
thermoacoustic instability specifically in the afterburner. The afterburner is modelled as a …

Model predictive control (MPC) has been used successfully in diverse applications. As its
name suggests, MPC requires a model for predictive optimization. The present paper …

An open–open organ pipe burner (Rijke tube) with a bluff-body ring was used to create a
self-excited, acoustically-driven, premixed methane–air conical flame, with equivalence …

A Rijke tube with a distributed heat source is investigated. Driven by the widely existing
thermoacoustic instability in lean premixed gas turbine combustors, this work aims to …

In this paper, of primary concern is a time-delayed thermoacoustic system, viz. a horizontal
Rijke tube. A continuation approach is employed to capture the nonlinear behaviour …

Thermoacoustics is concerned with the interactions between heat (thermo) and pressure
oscillations in gases (acoustics). A “Rijke Tube”, named after its inventor, is a fundamental …

Jet engines have remained almost entirely mechanical machines for fail-safe reasons,
despite the increasing sophistication of modern gas turbines. However, the trend goes …
