Abstract

The correlation-based γ-Reθt transition transport model has been implemented into a hybrid Reynolds-Averaged Navier-Stokes solver and evaluated on various basic test cases. The present work deals with the application of the γ-Reθt transition transport model to more complex and industrially relevant aerodynamic configurations. Results are shown for the computation of flow around a 2D high-lift airfoil and a 3D helicopter fuselage. The computed transition locations as well as the pressure and skin friction coefficient distributions are presented. The influence of the model specific parameters, the turbulence intensity and the turbulent to molecular viscosity ratio on the resulting transition locations is investigated. Modifications were applied to the original γ-Reθt transition model and the arising differences between the results are discussed.
