Abstract

The correlation-based γ-Reθt transition transport model was implemented in a hybrid Reynolds-averaged Navier– Stokes solver and validated on various test cases. The γ-Reθt model predicts two-dimensional transition phenomena such as transition due to Tollmien–Schlichting instabilities and separation-induced transition. The present work includes results for the application of the γ-Reθt to two three-dimensional test cases, which are the 6∶1 inclined prolate spheroid and the ONERA M6 wing. Depending on the flow conditions, the computational results are in good agreement with the experimental data. Once the given flow conditions lead to three-dimensional transition phenomena, the transition prediction with the γ-Reθt model is not reliable, because the model is based on the characteristics of two-dimensional boundary layers and three-dimensional transition mechanisms are not taken into account. To close this gap, the γ-Reθt model was extended by an approach that accounts for transition due to crossflow instabilities in three-dimensional boundary layers. This approach and its implementation into the original model are introduced. First results for the flow over two different infinite swept wing configurations, which are the ONERA D wing and the NLF(2)-0415 wing, are presented.
