Abstract

Background. In order to investigate the effect of aerodynamic characteristics of S series airfoils on the straight-bladed vertical axis wind turbine (SB-VAWT), numerical simulations and wind tunnel experiments were carried out using a small SB-VAWT model with three kinds of blade airfoils, which are asymmetric airfoil S809, symmetric airfoil S1046, and NACA0018 used for performance comparison among S series. The aerodynamics characteristics researched in this study included static torque coefficient, out power coefficient, and rotational speed performance. The flow fields of these three kinds of blade under static and dynamic conditions were also simulated and analyzed to explain the mechanism effect of aerodynamic performance. According to the results, the SB-VAWT with airfoil S1046 has better dynamic aerodynamic characteristics than other two airfoils, while the SB-VAWT with airfoil S809 is better in terms of the static characteristics. As the most suitable airfoil for SB-VAWT, the S series airfoil is worth researching deeply.

S系列翼型直叶片垂直轴风力发电机气动特性研究

背景为了研究S系列翼型的气动特性对直叶片垂直轴风力涡轮机（SB-VAWT）的影响，使用小型SB-VAWT模型对三种叶片翼型进行了数值模拟和风洞实验，以及NACA0018，用于S系列之间的性能比较。本文研究的空气动力学特性包括静态转矩系数、输出功率系数和转速性能。对这三种叶片在静态和动态条件下的流场进行了模拟和分析，以解释气动性能的机理影响。结果表明，S1046翼型的SB-VAWT具有比其他两种翼型更好的动态气动特性，而S809翼型的SB-VAWT在静态特性方面更好。S系列翼型作为SB-VAWT最适合的翼型，值得深入研究。

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
