Abstract
Wind energy has always been a source of energy used by man, since ancient times with Dutch windmills and sailboats, but only nowadays has become the focus of great study. Given the economic viability of its use for large-scale electric power generation, the abundance of propitious regions in the Brazilian territory and its sustainable character, indispensable in the present day. There is thus the need to develop new technologies and components that optimize and at the same time reduce their cost, goals that inevitably use CFD tools. In this way, the objective of this work is to provide a detailed analysis of the performance of a large-scale horizontal axis wind turbine by the torque, power and pressure distribution coefficients using a CFD tool based on the Finite Volume method (Ansys Fluent 18.1®) for the resolution of the RANS equations. The mesh quality validation was given by the Grid Convergence Index (GCI), which analyzes how far the results are from the asymptotic solution (exact) for the mesh used.
