Diseño y simulación de un aerogenerador de eje vertical mediante Solidworks Flow Simulation para hallar los coeficientes estáticos de torque

Abstract

The adoption of Sustainable Development Goals and new regulations associated with renewable energies in our country, combined with wind potential, promoted the development of renewable energies at all levels. Today, low-power technologies are possible solutions to problems of electricity supply faced by areas far away from big cities. Vertical axis wind turbines are considered less efficient than the conventional horizontal axis wind turbines, so it is relevant to carefully study its aerodynamic characteristics. In this work, static torque coefficients of a Savonius wind turbine with semicircular blades, overlap ratio of 0,15 and Reynolds number of 120.000, were investigated numerically using SolidWorks Flow Simulation® and using models that were expermientally corroborated by Kamoji, Kedare y Prabhu. Static torque coefficients were found by a calculation method using pressure values obtained by Computacional Fluid Dinamic. Furthermore, this work proposed that by this method for evaluated static torque coefficients, optimal overlap ratio can be found and examined self-starting capability.
