A model for the prediction of laminar-turbulent transition processes was formulated. It is based on the LCTM ('Local Correlation-based Transition Modelling') concept, where experimental correlations are being integrated into standard convection-diffusion transport equations using local variables. The starting point for the model was the γ -Re θ model already widely used in aerodynamics and turbomachinery CFD applications. Some of the deficiencies of the γ -Re θ model, like the lack of Galilean invariance were removed. Furthermore, the Re θ equation was avoided and the correlations for transition onset prediction have been significantly simplified. The model has been calibrated against a wide range of Falkner-Skan flows and has been applied to a variety of test cases.
