WebFeb 1, 2024 · Rayleigh-Brillouin spectral profiles are measured with a laser-based scatterometry setup for a 90° scattering angle at a high signal-to-noise ratio (r.m.s. noise … WebRayleigh scattering can be defined as scattering in the small size parameter regime x ≪ 1. Scattering from larger particles is explained by the Mie scattering for an arbitrary size parameter x. For small x the Mie theory reduces to the Rayleigh approximation. It can be seen from the above equation that Rayleigh scattering is strongly ...
WebRayleigh-Bénard convection. This invaluable book presents a concise but systematic account of the formation of spatial flow structures in a horizontal fluid layer heated from below. Flows of this type, known as Rayleigh-Bénard convection, show important features of behaviour inherent not only in various hydrodynamic-instability phenomena but ...
