Estudio y experimentación del funcionamiento de un modelo de rotor eólico por medio de análisis dimensional y similitud para evaluar el potencial eléctrico disponible en la ciudad de Riobamba.

Abstract

This research work is aimed to determine the electrical potential available in Riobamba city by using a wind rotor model taking into account the existing wind potential. The state of the art of this type of experiments was studied in this experimental work, in addition, the scaling coefficients were investigated, analyzed and determined complying with the laws of geometric similarity, kinematics and dynamics between models and prototypes and also taking into account the π theorem by Vaschy-Buckingham to determine the dimensionless numbers. After that, the CAD modeling of the wind turbine model in solidworks was carried out for its subsequent analysis by means of finite elements. The wind rotor modeling was manufacture by using the 3D printing technique in order to know the flow lines behavior. Equipment and elements that allowed to acquire reliably data was implemented in the wind tunnel, the data acquired were the wind speed, the electrical power generated by the wind rotor model and the shaft rotational speed. The experimental trials were carried out with the data from the wind power potential of Urbina an Atillo, obtaining an electrical power of 0.52 [W] IN Atillo and 1.25 [W] in Urbina. So, it was determined that the implementation of a wind farm is viable since the prototype will have an approximate generation capacity of 1750 [KW]. It is recommended to continue with research between models and prototypes not only in the power generation field, but also in other areas based on the methodology proposed in this experiment.
