Diseño y optimización del álabe de un aerogenerador de eje horizontal de baja potencia y baja.

Abstract

ne of the most important aspects to take into account for the aerodynamic design of low power, low-speed horizontal-axis wind turbines is the use of aerodynamic profiles that make up the propeller blades, especially to increase efficiency at the time to capture the kinetic energy of the wind and reduce the cost of it. This work focuses on the design of the aerodynamic profiles of a blade for a low-power, low speed, horizontal-axis wind turbine, through the use of numerical optimization. We propose a combination of theories with which we seek to improve the accuracy and reliability of the design. In addition to a numerical parameterization for the modeling of the curves and the surfaces that are composed. In the first place, all the mathematical theoretical foundation is described, with which the necessary concepts for the design of the aerodynamic profiles will be understood. Next, we present the theories of design and optimization, applied through the use of a series of algorithms, as well as programs in Python language, thus generating an executable written in the same language, which facilitates the interaction of these theories with the user . The final part of this work is dedicated to illustrate the solution of the results in relation to the power coefficient. The results are discussed and compared with existing profiles.
