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 …
WebFeb 20, 2024 · An expression for resolving power is obtained from the Rayleigh criterion. In Figure 27.6. 6 a we have two point objects separated by a distance x. According to the Rayleigh criterion, resolution is possible when the minimum angular separation is.
