The turbulent transition process plays a critical role in the aerodynamic design of wind turbine rotors. Analysis tools such as Computational Fluid Dynamics must accurately predict the boundary layer transition process to be successfully applied to wind turbine design. Early work in the transition modeling field, performed by Langtry and Menter, focused on the coupling of a local correlation based transition model with the SST turbulence closure. This transition modeling approach, referred to as the γ-Reθ model, proved to be very successful in a number of industries, wind power included.
