Rayleigh index

WebThe Rayleigh distribution arises as the distribution of the square root of an exponentially distributed (or \chi^2_2 χ22 -distributed) random variable. If X X follows an exponential distribution with rate \lambda λ and expectation 1/\lambda 1/λ, then Y=\sqrt {X} Y = X follows a Rayleigh distribution with scale \sigma=1/\sqrt {2\lambda} σ ... 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.
