In the present paper, the aerodynamic analysis of two dimensional model of NACA 0012 airfoil is presented to improve their aerodynamic characteristics such us lift, drag coefficients and the lift to drag ratio for shape design of Horizontal-Axis Wind Turbine (HAWT).The Reynolds-averaged Navier Stokes (RANS) in conjunction with three turbulence models, namely, the Spalart Allmaras, the Transition kkL-omega and the k-ω shear stress transport (SST) are solved by using the commercial code ANSYS-FLUENT, a widely used finite-element method (FEM) based software in computational fluid dynamics (CFD).The computational domain was structured with 'C' topology block-structured mesh and the steady solver was used to capture the dynamic stall phenomena.Both grid and time step were optimized to reach independent solutions.Particularly a high quality 2D mesh was obtained using the ANSYS Meshing tool.Spatial discretization algorithm, interpolation scheme, pressurevelocity coupling and turbulence boundary condition were also optimized.The 2D CFD model was calibrated and validated comparing the numerical results with experimental data, available in scientific literature from National Advisory Committee for Aeronautics (NACA).As a result, a good agreement between numerical and experimental data was found.Then the blade element momentum method (BEM) which divides the blade into several blade elements used to calculate ideal geometry for a turbine blade.The present work represents the basis to develop an accurate three dimensional Horizontal-Axis Wind Turbine (HAWT) model and may be used to support wind tunnel experiments.
