Abstract

The work presents a CFD modeling using Comsol Multiphysics to find the optimal design of wind turbine airfoils. This study has two parts, the first part is to find the optimal angle of attack of the initial NACA airfoil in different operating conditions of a wide range of Reynolds number taking into account the aerodynamics performance before and after optimization. The second part is to study the effect of decoupling camber and its position as control shape parameters on the aerodynamics performance as objectives function with varying thickness of airfoils. The results illustrated that, compared to an initial NACA 4digit airfoil, the optimized airfoils lift to drag ratio was improved over a wide range of Reynolds number and the maximum thickness of airfoil. The results showed also that the blade with the optimized airfoil has a higher efficiency.
