Research on Blade Profile of Savonius Wind Turbine Based on NACA Airfoil
摘要: 阻力型垂直轴风力机由于其优越的环境适应性以及风向无关性等特征广泛运用于城市和乡村等低风速环境中。为提高阻力型垂直轴风力机的风能利用率，本文创新性的提出一种基于NACA翼型型线的Savonius风力机，并采用非定常数值模拟及翼型参数化研究了关键设计参数对风力机气动和流动特性的影响。结果表明：基于NACA翼型型线设计的Savonius风力机叶型不但提升了风力机的功率系数，还加宽了有效的工作范围；其中3040型风力机最佳功率系数为0.2357，高出传统Savonius风力机7.68%；基于NACA翼型的叶型能有效改善风力机流场，增大推动压差，减弱叶型分离涡，从而提高风力机的功率输出。
Abstract: The drag-type vertical axis wind turbine is widely used in low wind speed areas such as cities and villages due to its superior performance in complex wind environments and wind direction inde-pendent. In order to improve the wind energy utilization rate of the drag-type vertical axis wind turbine, this paper innovatively proposes a Savonius wind turbine based on NACA airfoil profile, and uses unsteady numerical simulation and airfoil parameterization to study the influence of key design parameters on the aerodynamic and flow characteristics of the wind turbine. The unsteady numerical simulation is carried out to study the influence of design parameters on the performance of the wind turbine. The results show that the blade profile of Savonius rotor based on NACA airfoil can not only effectively improve the power coefficient of the wind turbine, but also broaden the working and operation range. The wind turbine with 3040 blade profile achieves the best power coefficient 0.2357, which is 7.68% higher than the traditional Savonius wind turbine. At the same time, the blade profile based on NACA airfoil can effectively change the flow field around the wind turbine, increase the driving pressure difference of the wind turbine, reduce the size of shedding vortex, and thus improve the power output of the wind turbine.
