Kurzfassung
The capabilities of Reynolds stress model compared to eddy-viscosity RANS turbulence models and scale-resolving simulation methods for the flows characterized by separation from smooth surfaces and subsequent vortex formation are assessed. To this end, the flow over a delta wing and a diamond wing at the incidence angle of 13 deg. and 12 deg., respectively, are investigated. Predictions obtained for the aforementioned configurations by different approaches are compared to each other and to experiments. In this paper, improvements and detriments observed in Reynolds stress model predictions compared to RANS predictions and to scale-resolving simulations are presented.
