Abstract

Transition transport equation approaches have specific advantages in comparison to classical streamline-based methods as, for example, the eN-method, especially for the aerodynamic analysis of very large, complex aircraft configurations. For complex configurations, it was shown for many cases that Reynolds stress models can yield more accurate predictions than eddy viscosity turbulence models if the corresponding numerical results are compared to measured data from experiments. In this thesis the coupling of a Reynolds stress model with a transition transport model and the extension of the transition model for the prediction of crossflow transition are provided. Through investigations based on a large number of test cases including simple and complex flows and geometries the predictive potential of the coupled models is demonstrated. The implementation of the 9-equation model was carried out and all numerical results have been obtained using the unstructured DLR TAU code.
