CFD analysis of NACA4415 airfoil with γ−Reθ model considering natural transition
Airfoil analysis is essential to wind turbine aerodynamics. In typical operating conditions, airfoils undergo transition from laminar to turbulent flow in the boundary layer in a manner that must be modeled accurately to predict airfoil lift and drag. There are different modes of transition (e.g....

| description |
Airfoil analysis is essential to wind turbine aerodynamics. In typical operating conditions, airfoils undergo
transition from laminar to turbulent flow in the boundary layer in a manner that must be modeled accurately
to predict airfoil lift and drag. There are different modes of transition (e.g. natural, by-pass, wake induced,
reversed, separated flow) and modeling them is not straight-forward. Over the years, diversified predictions
have been developed for the various modes. One of the popular transition models is the local correlation-based
$\gamma-Re_\theta$ model of Menter et al. \citep{Menter2004}. The model requires data correlations for the
transition length and the critical Reynolds numbers. |
