    A new approach for designing small horizontal axis wind turbine blades
    (American Institute of Physics, 2024) Deghoum, Khalil; Al-Tamimi, Adnan N. Jameel; Gherbi, Mohammed Taher; Hamidatou, Smail; Abdullah, Oday Ibraheem
    In recent years the importance of wind energy has been increasing to be one of the most important renewable energy sources. In this study, the blade design of a small 5 kW wind turbine was optimized to obtain an optimal shape in order to increase the power and facilitate the fabrication process. The Betz method and the linearization design method was adopted to design the new shape. Using the blade element momentum theory (BEM), to compare the results of the initial design and linear design. Based on obtained results, it was found that the coefficient of power of the initial design is 0.44 at TSR equal to 6, while the new linear design is 0.47 at TSR equal to 5, meaning that there is an improvement of 6.38%, as the increase in power for the new design appears at lower speeds.

    Optimization of small horizontal axis wind turbines based on aerodynamic, steady-state, and dynamic analyses
    (MDPI, 2023) Deghoum, Khalil; Gherbi, Mohammed Taher; Sultan, Hakim S.; Mechakra, Hamza
    In this article, the model of a 5 kW small wind turbine blade is developed and improved. Emphasis has been placed on improving the blade’s efficiency and aerodynamics and selecting the most optimal material for the wind blade. The QBlade software was used to enhance the chord and twist. Also, a new finite element model was developed using the ANSYS software to analyze the structure and modal problems of the wind blade. The results presented the wind blade’s von Mises stresses and deformations using three different materials (Carbon/epoxy, E-Glass/epoxy, and braided composite). The modal analysis results presented the natural frequencies and mode shapes for each material. It was found, based on the results, that the maximum deflections of E-glass, braided composite and carbon fiber were 46.46 mm, 33.54 mm, and 18.29 mm, respectively
