Dowling, AP and Hubbard, S (2000) Instability in lean premixed combustors. Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 214. pp. 317-332. ISSN 0957-6509

A generalized acoustic equation is used to identify the mechanisms driving combustion instability. The relationship between the unsteady rate of heat release and the flow is found to influence significantly the frequency of oscillation. A kinematic flame model is reviewed and used to describe the unsteady combustion in a premixed ducted flame and in a typical lean premixed industrial gas turbine. Comparison is made between theory and experiment.
