Abstract
The Stress-omega differential Reynolds stress model with the omega-equations of Wilcox, Kok and Menter and the SSG/LRR-omega model, being always linked to the Menter omega-equation, have been applied to the transonic flow around the RAE 2822 airfoil and the ONERA M6 wing. Comparison with the Wilcox k-omega model shows the influence of replacing the k-equation and the Boussinesq hypothesis by the modeled Reynolds stress transport equation. Particularly for the M6 wing differential Reynolds stress models appear to be generally superior. Nevertheless the comparison between different model variants reveals, that details of the length scale equation can have a larger influence than details of the re-distribution term modeling.
