Wind energy has been seen as one of the most suitable
sources of renewable energy. Wind energy is low cost when compared the other sources.
Therefore, wind energy can gain an edge over the fossil-fired power plants. Aerodynamic
efficiency of the airfoil is very crucial for aerodynamic efficiency of the wind
turbine. The primary purpose of our study was to analyze the NACA0012 and NACA4412
airfoil at various attack angles with constant Reynolds number and to examine the
effects of the symmetrical and asymmetrical profiles of the airfoil. Analysis of
aerodynamic performance of NACA0012 and NACA4412 airfoil were performed with using
ANSYS Fluent program. Also, lift coefficients and drag coefficients were calculated
at various attack angles.  According to calculations,
optimum attack angles were found for each profile. Finally, NACA0012 and NACA4412
airfoils were discussed and reported in terms of their airfoil performances.
