Sensitivity of the Rayleigh criterion in thermoacoustics

Web1 Introduction. 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 … WebTo obtain a good image, point sources must be sufficiently far apart that their diffraction patterns do not overlap.

WebJan 19, 2024 · The Rayleigh Criterion is a slightly refined formula based on Abbe’s diffraction limits: R = 1.22λ/(NA obj + NA cond) where λ is the wavelength of light used to image a specimen. NA obj is the NA of the objective. NAcond is the NA of the condenser. The value ‘1.22’ is a constant. This is derived from Rayleigh’s work on Bessel Functions. http://contents.kocw.or.kr/document/optical-physics-10.pdf
