National finalist JAMES DYSON AWARDS, 2015.
ei! award winner. Best Final Degree Project - Product Design Category, 2014.
OXO was designed in order to develop a power generation system through the wind. The main objective is to address the energy needs of the yachts participating in the Barcelona World Race. This system generates renewable energy through an innovative, safe and efficient process.
The exploded view shows the aerogenerator components. It mostly consists of carbon fiber; other important components of different material are the bearings and generator.
Carbon fiber used is a bidirectional prepreg (twill prepreg 2: 2). It was chosen for design reasons and common and simple fabrication methods. The bearings are placed in the wind turbine tower, and allowing the top is adjustable ensuring its relative rotation relative from the lower part, that is fixed. The material selected was the POM.
Total weight is 14,44 Kg; it should be noted that the generator, a standar component, provides
6 Kg of the total weight.
The air is collected through the entire upper ring and driven toward the interior where the blades and the generator placed. As air travels through the interior of conduction the flow increases, at the end the section gets smaller and the speed increases. It is represented graphically in the
The simulation of fluids is important on the one below. It is noted, theoretically, OXO operation. Initial conditions were fixed which the wind speed of 11 m/s (22 knots); this value is the average speed obtained in the last race.
The results show that in the initial channelling is produced an average increase of 23.7% in the wind speed. The maximum speed is located at the output point and it’s 16.46 m/s which means an increase of 45.45%.
