Abstract

A quantitative model for turbulent channel flow is presented, based on the multi-layer hypothesis and the Lie-group analysis. The model describes the mean velocity profiles in the whole flow domain at a large range of Reynolds numbers (Re)-in a good agreement with present DNS results. This result is a systematic application of structural ensemble dynamics (SED) approach, which is equally applicable to other flows such as incompressible and compressible boundary layers, thus shedding light on a viable theory for complex turbulence.
