- •
A calibration study of the k-omega SST turbulence model for small scale wind turbines.
- •
Two sets of blades were designed, built, field tested and numerically simulated.
- •
Both the NACA 0012 (symmetrical) airfoil and the NACA 4412 (cambered) were used.
- •
The k-omega SST model was calibrated changing the β* value.
- •
For the two sets of blades, the lowest RMSE value was obtained for β* = 0.27.
