Linear thermoacoustic instability in the time domain
The Journal of the Acoustical Society of America, 1998An approximate time-domain description of the development of the thermoacoustic instability in gas-filled tubes is developed by exploiting the difference between the instability time scale and the period of standing waves. The perturbation results compare very favorably with the exact frequency-domain theory of Rott.

Thermoacoustic Instabilities in Counterflow Diffusion Flames
2019Thermoacoustic 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 extensively with regards to premixed flames, where the fuel and oxidizer are fully mixed before combustion, the study of thermoacoustics in diffusion flames

Impact of Linear Coupling on Thermoacoustic Instabilities
Combustion Science and Technology, 2008There have been conflicting opinions in literature, about the consequences of ignoring the linear coupling terms in finite-dimensional thermoacoustic models. We try to clarify this issue in this paper. We study consequences of ignoring the linear coupling terms on the non-normal thermoacoustic interactions in a horizontal Rijke tube.
