Maassen van den Brink, A. TNO Fysisch en Elektronisch Laboratorium Contributor Benzi, R. (editor) Publication year 1995 Abstract Turbulence mixing is treated by means of a novel formulation of nonlocal K-theory, involving sample paths and a stochastic hypothesis. The theory simplifies for mixing by exchange (strong-eddies) and is then applied to the boundary layer (involving scaling). This maps boundary layer turbulence onto a nondiffusive (Kubo-Anderson or kangaroo) type stochastic process. The theory involves an exponent epsilon (with the significance of a Cantor set dimension if epsilon is less than 1). With expsilon approximately equal to 0.58 (epsilon approaches infinity in the diffusion limit) the ensuing mean velocity profile U-bar+ = f(y+) is in perfect agreement with experimental data. The near-wall (y approaches 0) velocity fluctuations agree with recent direct numerical simulations Subject PhysicsTurbulent boudary layerStochastic processesTurbulent mixingFlow theoryVelocity distributionReynolds equationNavier-Stokes equations To reference this document use: http://resolver.tudelft.nl/uuid:c837fc1f-fed5-48c2-bdb2-8fd48df1bab0 TNO identifier 94817 Publisher Kluwer Academic Publishers, Dordrecht Source Advances in Turbulence V - Proceedings of the Fifth European Turbulence Conference, Siena, Italy, 5-8 July 1994, 100-104 Document type conference paper Files To receive the publication files, please send an e-mail request to TNO Library.
