Abstract

This report describes the implementation, verification, and validation of the Wilcox stress-w and the SSG/LRR-w Reynolds stress models into the DLR-FLOWer code within the EU-project FLOMANIA. The model equations are summerized, and their implementation into DLR's structured flow solver FLOWer is briefly described. The implementation is verified by comparison with results for a turbulent flat plate boundary layer with zero pressure gradient and the incompressible flow through an asymmetric diffuser, chosen as mandatory test case in FLOMANIA. Validation is carried out for the airfoil RAE 2822 for the so-called cases 9 and 10, for the Aérospatiale A airfoil at alpha = 13.3° and for the ONERA M6 wing at alpha = 3.06°.
