Asymptotic Analysis of Turbulent Channel Flow for Mean Turbulent Energy Closures.

Abstract

The Reynolds time-averaged equations are adopted for fully turbulent two-dimensional flow of an incompressible fluid through a channel with plane smooth walls. Closure is effected by means of so-called second-order methods based on the conservation of mean turbulent kinetic energy. In particular, generalizations of the turbulent shear flow models due to Bradshaw, Ferriss, and Atwell and to Spalding and co-workers, are adopted as representative of recent differential closure models. The models are treated in the limit of large turbulent Reynolds number by means of limit-process expansions. (Author)
