The extension of the local correlation-based γ-Reθt transition transport model for the prediction of transition due to crossflow instabilities for three-dimensional aerodynamic configurations was already introduced by the authors. Based on this work, the extended model was partly modified and further developed. The details of the latest version of the extended model are given in the present work. The local computation of relevant model quantities within a finite-volume based numerical flow solver is presented. Based on results from computations for an infinite swept wing the characteristics, the application range and the mesh sensitivity of the extended model are shown. Results of the application of the extended model to three-dimensional test cases are given and improved transition prediction capabilities for these cases are demonstrated. Finally, results, open questions and limitations of the model approach are discussed.
