Abstract

Abstract Turbines are one of the most important means of producing clean energy, as they do not cause any negative emissions affecting the environment. Recently, the need to design turbines capable of facing strong winds has appeared because the currently designed turbines must be cut off in such circumstances. This study aims to find the best design parameters and investigate the efficiency of the jet turbine at high wind speed conditions. SolidWorks and MatLab are used to design and analyze small jet wind turbines. The design parameters were chosen to obtain the best efficiency. The turbine diameter is 0.5 m, and the short blade length helps withstand the generated stresses due to strong wind, especially fatigue stress, and resists bending. Blade pitch angle beta starts from 2° from the vertical axis at the hub and changes harmonically along the length to end at an angle of 88° at the blade’s tip to allow air to pass through and not form a wall. The blade number has chosen 15 blades, corresponding to the Betz limit, to obtain the maximum power coefficient. As a result, the assigned power was obtained at a wind speed of 28 m/s. At a lower wind speed, it will work with acceptable efficiency and more efficiently at higher speeds. Therefore, this turbine is suitable to use in such cases.

高风速条件下射流风力机的设计参数与机械效率

涡轮机是生产清洁能源的最重要手段之一，因为它们不会产生任何影响环境的负排放。最近，由于目前设计的涡轮机在这种情况下必须切断，因此出现了设计能够面对强风的涡轮机的需求。本研究旨在寻找最佳设计参数，研究喷气涡轮在高风速条件下的效率。利用SolidWorks和MatLab对小型喷气风力发电机进行了设计和分析。设计参数的选择是为了获得最佳的效率。涡轮直径为0.5 m，叶片长度短，有助于承受强风产生的应力，特别是疲劳应力，并抗弯曲。叶片俯仰角β从2°开始从垂直轴在轮毂和变化沿长度和谐在88°的角度在叶片的尖端结束，以允许空气通过，而不是形成一个墙。叶片数选择了15片叶片，对应贝茨极限，以获得最大功率系数。因此，在风速为28 m/s时获得分配功率。在较低的风速下，它将以可接受的效率工作，在较高的风速下效率更高。因此，这种涡轮机适合在这种情况下使用。
