WebMar 28, 2006 · The Rayleigh problem, whose vorticity equation is simply ∂Ω/∂ t = ∂ 2 τ/∂ y2, is introduced as a setting for Townsend's theory. Certain wall speed programmes are shown to generate Rayleigh layers that are exactly self-similar in the fully turbulent part of the flow. Those layers correspond to Clauser's equilibrium boundary layers.

WebA complication with the Rayleigh damping model is to obtain good values for the damping parameters α dM and β dK. A more physical damping measure is the damping ratio, the ratio between actual and critical damping, often expressed as a percentage of the critical damping. Commonly used values of the damping ratio can be found in the literature. WebAug 24, 2007 · Rayleigh fading channel is the foundation of mobile radio channel modeling.
