Rayleigh index
WebJun 6, 2024 · The Rayleigh equation describes a typical non-linear system with one degree of freedom which admits auto-oscillations (cf. Auto-oscillation ). This equation was named after Lord Rayleigh, who studied equations of this type related to problems in acoustics [1] . If one differentiates equation (*) and then puts $ y = \dot {x} $, one obtains the ... WebMar 17, 2024 · A Rayleigh distribution has positive asymmetry; its unique mode is at the point $ x = \sigma $. All moments of a Rayleigh distribution are finite, the mathematical expectation and variance being $ \sigma \sqrt {\pi /2 } $ and $ 2 \sigma ^ {2} ( 1 - \pi / 4 ) $, respectively. The distribution function of a Rayleigh distribution has the form

WebThe Rayleigh index is used to identify local regions in the combustor which are responsible for driving and damping the instability. By comparing the Rayleigh index to flowfield parameters it is possible to connect damping and driving to specific flowfield conditions. http://plaza.ufl.edu/dwhahn/Rayleigh%20and%20Mie%20Light%20Scattering.pdf
