“…To protect our environment, the world seeks alternative energy sources that are environmentally friendly. Among these sources, wind energy is one of the most promising alternative energy sources [1]. It is the second most mature technology to capture power from alternative sources just after hydropower.…”

The field of wind energy has made significant progress, yet there is always room for improving efficiency and the energy extracted from horizontal axis wind turbines HAWTs. There is interest in new renewable energies, including wind energy. This study aims to investigate the effect of trailing edge flap on the performance of the turbine at different numbers of blades, different blade angles, and flap angles. Therefore, an experimental setup includes a model of wind turbine was constructed. The performance of a HAWT model with trailing edge flaps added is examined in this research using the findings of wind tunnel tests. A model with two, three, and six-bladed rotors with a diameter of 260 mm was employed for the wind tunnel tests. The wind turbine model is tested at various blade angles and tip speed ratios. The model was initially tested at various blade angles without any flaps, β, of 10 o , 15 o and 20 o , with two, three, and six-bladed rotors and secondly the wind turbine model was tested with additional trailing edge flaps with flap angle, α, of 40 o , 50 o and 60 o . It was found that the use of trailing edge flaps can improve the HAWT performance.

En el presente trabajo se desarrolló el estudio de un rotor de aerogenerador Darrieus tipo Phi de 2 m de altura (para baja potencia) mediante los métodos Double Multiple Streamtube (DMS) y Qblade lifting line theory (QLLT) con la finalidad obtener los parámetros de configuración adecuados para el posterior diseño de un aerogenerador de eje vertical (VAWT) de dimensiones similares. Se realizó la comparación de ambos métodos con resultados experimentales reportados por otros autores, utilizando como referencia la estimación del coeficiente de potencia (Cp) en función de la relación de velocidad específica (TSR). Se encontró que el método QLLT es una mejor solución en términos de estimación del coeficiente de potencia, con un error absoluto máximo de 35 % y error promedio de 5 %. Sin embargo, dado el alto tiempo de cómputo en comparación con el método DMS es recomendable su uso en etapas avanzadas de diseño. Por otro lado, el método DMS con una capacidad de estimación inferior (error absoluto máximo de alrededor de 60 %, error promedio de 11 %) es adecuado para las primeras etapas de diseño dado su bajo tiempo de Cómputo.
