Abstract

A simplified consistency condition for the production-to-dissipation ratio is developed to obtain an explicit algebraic Reynolds stress model. The stress expression is based on the well-known tensor representation derived from quasi-linear pressure–strain correlation models for two-dimensional mean flows in the weak-equilibrium limit. Results obtained for homogeneous turbulent flows, a backward-facing step flow, and a channel bend flow indicate that the model combines improved accuracy with computational efficiency.
