The most commonly used criterion to assess the stability of a thermoacoustic system, such as a gas turbine combustor or a rocket motor, is the Rayleigh criterion (Lord Rayleigh 1878).This criterion states that the acoustic energy increases when the heat-release rate is sufficiently in phase with the acoustic pressure that the work done …
