المستخلص: This paper is aimed perform aerodynamic simulations around HAWT blades and design blades, small wind turbine produce 2kw of electricity. In this research using Gambit software for Design and ANSYS fluent for simulation to develop the system dynamic modelling. The data in the wind speed model can be obtained from experiment of wind applications in Libya support and implement this technology, to improve services in rural villages in Libya. The blade is made up of single air foil. The chord length is variable throughout the blade. Chose NACA 4412 because life coefficient is high. Previous simulation kinds of air foils ( NACA 4412, NACA 4415, NACA 63-006, NACA 24112, NACA 63-215 and NACA 1410.). Also lift and drag coefficient ratio (Ci/CD) for NACA 4412 air foil higher than NACA 4415 air foil. So NACA 4412 good performance. In this study 2D air foil (NACA 4412) CFD models is presented by ANSYS-FLUENT software, using the k-epsilon turbulent viscosity in this simulation, the lift, drag and moment coefficients were calculated for air foil NACA 4412 at various angles of attack (0,5,10,15,20). Laminar to Turbulent flow structures near and far fields of the rotor region are characterized for average the wind speed of 5m/s and the rotor speed of 72 RPM. Meshing volume is done by ICEM software, the number of elements in the mesh used for simulations is (398436). The torque generated by the turbine is (30.3084 N.m) and the power generation of the turbine is 2kw.
