In this work it was performed a numerical and experimental investigation of the aerodynamic performance of two small three-bladed wind turbines with diameter of 3m. The airfoils used, NACA 0012 (symmetrical) e NACA 4412 (unsymmetrical), were designed for low speed applications, such as the horizontal axis wind turbines. The wind turbines were built and tested at the Solar Energy and Natural Gas Laboratory –UFC. This allowed the attainment of the performance curves, enabling the comparison between the results of the numerical analysis. In order to calibrate the turbulence model k-ω SST to applications in small wind turbines, it was performed numerical simulations using the open source package for CFD solutions OpenFOAM, version 1.7.1. The nu...
