Abstract

A series of experiments were conducted to study the effect of leading-edge roughness on the state of the boundary layer of a wind turbine blade section using multiple hot-film sensors. The experiments involved static and dynamic tests, where airfoil motion was of plunging type [...]

Abstract

A novel control method for a fixed-pitch variable speed wind turbine is introduced and experimental results are presented. The measured absorbed power and rotational speed, together with a look-up table for the aerodynamic efficiency, are used to estimate the wind speed reaching the [...]

Abstract

In this paper, the design and aerodynamic simulation of a rotor for horizontal axis wind turbine for the Cerro Villonaco was carried out. The aerodynamic design aimed for a blade with an optimal geometry, which is defined by the chord and the twist angle of the airfoil. The design [...]
