Nonlinear Thermoacoustic Instability Dynamics in a Rijke Tube
Combustion Science and Technology, 2012We present a data-driven nonlinear and chaos theory–based analysis of thermoacoustic instabilities in a simple Rijke tube. Thermoacoustic instability modes in this simple Rijke tube display very rich nonlinear behavior because of the interaction of acoustic modes and unsteady heat-release processes during combustion.

Stability and Control of a Thermoacoustic Device: The Rijke’s Tube
Volume 2: Dynamic Modeling and Diagnostics in Biomedical Systems; Dynamics and Control of Wind Energy Systems; Vehicle Energy Management Optimization; Energy Storage, Optimization; Transportation and Grid Applications; Estimation and Identification Methods, Tracking, Detection, Alternative Propulsion Systems; Ground and Space Vehicle Dynamics; Intelligent Transportation Systems and Control; Energy Harvesting; Modeling and Control for Thermo-Fluid Applications, IC Engines, Manufacturing, 2014This study presents an intersection of two seemingly separate areas of research frontiers, “prediction and control of thermoacoustic instability” and “stability analysis of neutral-class linear-time-invariant (LTI) and time-delayed systems (TDS)”. The former is a coveted capability which has been elusive to the scientific community over 1½ centuries ...

Non-linear response of a generalized Rijke tube
International Journal of Engineering Science, 2001The mathematical model of unsteady velocity sensitive thermoacoustic interactions in a heated duct (generalized Rijke tube) reported by the authors in a previous publication is used to predict non-linear response. Both closed form and numerical solutions of equations derived by an approximate modal analysis are presented and employed to illustrate and ...

A Model of Heat Transfer in Rijke Tube Burners
Combustion Science and Technology, 1996Abstract This paper presents a simple velocity transfer function for use in analysing the acoustic characteristics of Rijke Tube burners. The use of the transfer function is first demonstrated for predicting gauze tone amplification of a Rijke Tube burner when the flame/gauze system is situated in the lower quadrant of an entirely open tube.

Suppression of Rijke tube oscillations by delay coupling
Journal of Applied Physics, 2020This study experimentally analyzes the cessation of self-sustained periodic oscillations of gas columns in delay-coupled Rijke tube oscillators. The Rijke tube oscillator comprised an open-ended resonance tube with a Bunsen burner inserted into it. Delay coupling was introduced using acoustic waves propagating through a gas-filled tube with both ends ...

Thermo-acoustic instability in the horizontal Rijke tube
Journal of Mechanical Science and Technology, 2006The instability curve of a Rijke tube system was obtained accurately by following different paths of heat power and flow-rate for three regions and by defining its locus from the criterion based on the measured sound pressure levels. The unstable limits in the region of flow-rate lower than that at the minimal power are compared with previous data.

Thermoacoustics and the Rijke Tube: Experiments, Identification, and Modeling
IEEE Control Systems, 2015The Rijke tube [1] is a classic experiment that is relatively simple and inexpensive to build in a typical university laboratory. Despite its construction simplicity, it can serve to illustrate a wide variety of mathematical modeling, empirical identification, verification, and feedback control techniques.

Energy consideration of the nonlinear effects in a Rijke tube
Journal of Fluids and Structures, 2003The goal of this work is to characterize the excited states of a thermoacoustic system with mean flow. The properties of excited regimes are determined by the balance between thermoacoustic energy transformation and acoustic losses. In many systems, the sound intensity is not sufficient for nonlinear acoustic losses to be a major factor in defining ...

Thermoacoustic instabilities in the Rijke tube: experiments and modeling
2003Thermoacoustic instability can appear in thermal devices when unsteady heat release is coupled with pressure perturbations. This effect results in excitation of eigen acoustic modes of the system. These instabilities are important in various technical applications, for instance, in rocket motors and thermoacoustic engines.
