Journal ArticleDOI
Acoustic Analysis of Gas Turbine Combustors
Ann P. Dowling,Simon R. Stow +1 more
TL;DR: In this article, a simplified combustion system, from compressor outlet to turbine inlet, is modeled as a one-dimensional mean with linear perturbations, which leads to predictions for the frequencies of oscillations and the susceptibility to instabilities for which linear disturbances grow expotentially in time.
Journal ArticleDOI
Reflection of circumferential modes in a choked nozzle
TL;DR: In this paper, small perturbations of a choked flow through a thin annular nozzle are investigated, and the boundary condition found by Marble & Candel (1977) for a compact choked nozzle is shown to apply to first order, even for circumferentially varying waves.
Proceedings ArticleDOI
Thermoacoustic Oscillations in an Annular Combustor
Simon R. Stow,Ann P. Dowling +1 more
TL;DR: In this article, a linear model for thermoacoustic oscillations in lean premixed prevaporised (LPP) combustors is described, where a thin annular combustor is assumed and circumferential modes are included but radial dependence is ignored.
Proceedings ArticleDOI
Low-Order Modelling of Thermoacoustic Limit Cycles
Simon R. Stow,Ann P. Dowling +1 more
TL;DR: In this article, a low-order model for thermoacoustic limit cycles in premixed prevaporised (LPP) combustors is described, based on the fact that the main nonlinearity is in the combustion response to flow perturbations.
Journal ArticleDOI
Model-Based Control of Combustion Instabilities in Annular Combustors
Aimee S. Morgans,Simon R. Stow +1 more
TL;DR: In this paper, a computational thermoacoustic model is used to simulate unstable annular combustors, providing a platform on which to develop and test control strategies, which can be used to stabilize combustion instabilities.
