• Abstract:

  Studies and research in wind energy have received great attention in recent years, mainly in the decentralized generation of electric energy, through small-size wind turbines. In this sense, the present work aims to validate a Computational Fluid Dynamics methodology for a case study of an H-Darrieus Vertical Axis Wind Turbine. The main recommendations of a robust reference methodology were replicated, which carried out a multivariate sensitivity analysis, using a transient two-dimensional simulation model and the sliding mesh technique to account for the turbine's rotational motion. Comparing the results from the simulation of the present work with the results of the reference methodology, satisfactory values were obtained, considering that the maximum difference in the final value of the Coefficient of Power was less than 9%. Furthermore, the torque profile of both studies was virtually identical. Based on these results, it was possible to conclude that the studied methodology was validated and, therefore, can be applied to other small-size H-Darrieus Wind Turbines, operating under similar operating conditions.
