Abstract

Bypass and laminar-separation-bubble induced transition phenomena are very common in turbine blade cascade flow with high turbulence environment. In order to predict the transition position and aerodynamic characteristics accurately in high turbulence environment, the similarity velocity profiles at various shape factors are obtained by solving the Falkner-Skan boundary layer similarity equations. Then, the local formulas of non-local variables are fitted based on the similarity velocity profiles and combined with a new indicator factor to form transition criterion, so as to construct the turbulence transition model. The transition model was used to predict and simulate the flows of zero pressure gradient plates, T3C series pressure gradient plates, and PAK-B turbine blade cascade. The predicted results under various turbulence and pressure gradients are all according with the experimental data. It proves to be that the model proposed in this paper is reasonable and feasible.
