Abstract
The two-dimensional numerical simulation for NACA0015 airfoil and S325 airfoil were conducted with k-ω SST turbulence model. For the k-ω SST turbulence model could not predict the airfoil stall characteristics accurately, the non-equilibrium turbulence transport nature was systematically analyzed. The study showed that: the turbulent viscosity scope simulated by the original k-ω SST turbulence model was smaller which resulting in the model could not accurately simulate the turbulence transport properties in the separation zone; By increasing β* or decreasing α1 can improve the capabilities for predicting the transport characteristics of non-equilibrium turbulent, and then improve the accuracy of numerical simulation for stall characteristics of the airfoil, it also helps to improve the accuracy of numerical simulation of wind turbine blades.
