Abstract
This paper consists in the creation of a methodology for obtaining the main characteristics of any small HAWT for tests realized in a modified EEE wind tunnel (Edibon) with a circular cross section of 0.55 m and a length of 2 m. The work is divided in three main parts. The first part describes all the equipment used during the experiments and the standard EEE wind tunnel’s turbine composed of 3 blades and a diameter of 0.5 m. The second part focus on the detailed procedure for the obtention of all needed data to evaluate the performance of the turbine. The last part consists of using Bahaj’s blockage correction method to correct all the power coefficient curves that were obtained. This correction was made due to the wind tunnel’s small cross section. The methodology showed satisfactory performance. The use of a smaller rotor to decrease the blockage ratio and sensors to obtain data with more accuracy are recommended to the upgrade of the methodology.
