The paper presents validation of -Reθ model proposed by Menter at al (2006), which was extended by in-house correlations on onset location and transition length. The tests performed were based on experimental data on the flat plate test cases where l-t transition, laminar separation and reattachment were present. The model was applied both for steady and unsteady calculations. It was shown that the model was able to reproduce some essential flow features related to the separated transition and the simulations reveal good agreement with the experimental results.
