Abstract: A new transition turbulence model is proposed. The model is based on the computation of the pre-transitional u′v′¯ due to mean flow shear. The proposed transition model is fully described and verified against standard benchmark test cases. A detailed analysis of its behavior is performed using the ERCOFTAC flat-plate T3A, T3B and T3C test cases. Further, the model is validated in terms of the pre-transitional computed u′v′¯ in comparison to experiments of ERCOFTAC database. The model presents very good results for bypass transition for flows with and without pressure gradient.
