Abstract Perturbations in a non-normal system can grow transiently even if the system is linearly stable. If this transient growth is sufficiently large, it can trigger self-sustained oscillations from small initial disturbances. This has important practical consequences for combustion–acoustic oscillations, which are a persistent problem in rocket and aircraft engines. Balasubramanian & Sujith (J. Fluid Mech., vol. 594, 2008, pp. 29–57) modelled an infinite-rate chemistry diffusion flame in an… 
Non-normality and nonlinearity in combustion–acoustic interaction in diffusion flames – CORRIGENDUM
Recent investigations by L. Magri and M. P. Juniper have brought to light certain errors in the paper by Balasubramanian and Sujith (Journal of Fluid Mechanics, vol. 594, 2008, pp. 29–57). The
Global modes, receptivity, and sensitivity analysis of diffusion flames coupled with duct acoustics
Abstract In this theoretical and numerical paper, we derive the adjoint equations for a thermo-acoustic system consisting of an infinite-rate chemistry diffusion flame coupled with duct acoustics. We
A systems perspective on non-normality in low-order thermoacoustic models: Full norms, semi-norms and transient growth
Non-normal transient growth of energy is a feature encountered in many physical systems. Its observation is intimately related to the norm used to describe the system dynamics. For a multi-physics

In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple with acoustic pressure oscillations. If the heat release is sufficiently in phase with the pressure, these
A Theoretical Approach for Passive Control of Thermoacoustic Oscillations: Application to Ducted Flames
In this paper, we develop a linear technique that predicts how the stability of a thermoacoustic system changes due to the action of a generic passive feedback device or a generic change in the base
Minimal energy thresholds for triggering in the Rijke tube: the effect of the time delay
Abstract Triggering is the process by which a linearly stable thermoacoustic system can reach self-sustained oscillations. This nonlinear phenomenon is activated only for sufficiently large
Thermoacoustic Instabilities in Counterflow Diffusion Flames
Thermoacoustic instabilities arise in combustion systems from a coupling between the unsteady heat release of the flame and the underlying acoustic field. Although thermoacoustics have been studied
