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.
