Verification and Validation of a Second-Moment-Closure Model

Abstract

The implementation of the combined Speziale-Sarkar-Gatski/Launder-Reece-Rodi differential Reynolds stress model into different flow solvers
\nis verified by studying the grid convergence of test cases from the Turbulence Modeling Resource Website.
\nThe model's predictive capabilities are also assessed based on four basic and three extended validation cases, involving attached and separated boundary layer flows, effects of streamline curvature and secondary flow.
\nSimulation results are compared against experimental data and predictions
\nby the eddy-viscosity models of Spalart-Allmaras and Menter's Shear Stress Transport.
