Experimental data of Hussein et al. (1993) for the turbulent round jet are used to evaluate individual components of Reynolds stress turbulence models. Models for terms in the Reynolds stress equations are reviewed, with particular emphasis on linear and nonlinear pressure-strain models. Improved coefficients for the Choi and Lumley return-to-isotropy expressions have been developed by the authors. These coefficients are valid for a wider range of flows than the currently used coefficients. Pressure-strain and transport model components are compared to the experimental data for the jet, and agreement is very good, indicating that the models are reasonably correct. Predictions using the linear models are generally as good as those obtained using nonlinear models, indicating that nonlinear models may not be necessary for engineering accuracy for this flow.
