An Alternative Assessment of Second-Order Closure Models in Turbulent Shear Flows

Abstract

The performance of three recently proposed second-order closure models is tested in benchmark turbulent shear flows. Both homogenous shear flow and the log-layer of an equilibrium turbulent boundary layer are considered for this purpose. An objective analysis of the results leads to an assessment of these models that stands in contrast to that recently published by other authors. A variety of pitfalls in the formulation and testing of second-order closure models are uncovered by this analysis.
