WebMay 22, 2024 · What is Rayleigh Number. The Rayleigh number is a dimensionless number, named after Lord Rayleigh. The Rayleigh number is closely related to Grashof number and both numbers are used to decribe natural convection (Gr) and heat transfer by natural convection (Ra). The Rayleigh number is simply defined as the product of the Grashof … Rayleigh scattering is an important component of the scattering of optical signals in optical fibers. Silica fibers are glasses, disordered materials with microscopic variations of density and refractive index.
