如今，风电已成为替代化石燃料发电最可靠的新能源之一，被誉为广泛分布的清洁可再生能源。它现在是世界上增长最快的能源，也成为发展最快的行业之一。风力涡轮机的空气动力学受转子周围的流动控制，其中预测不同运行条件下转子叶片上的空气载荷及其与转子结构动力学的关系对于设计目的至关重要。因此，风力涡轮机空气动力学中最重要的挑战之一是准确预测叶片上的力，其中叶片和尾流通过叶片单元动量（BEM）理论、涡流方法和计算流体动力学（CFD）等不同方法进行建模。本文采用涡流法研究风力机气动性能。研究了具有规定尾流模型的不同叶片模型，例如升力线和升力面。主要目的是找到影响气动载荷以及计算时间效率的叶片和尾流模型的适当组合。将不同方法的结果与 GENUVP 代码进行比较。 （参见致谢）
Today, wind power is one of the most reliable new energy source serving as an alternative to fossil-fuel generated electricity and is known as widely-distributed clean and renewable energy source. It is now the world’s fastest growing energy source and has also become one of the most rapidly expanding industries. The aerodynamics of a wind turbine are governed by the flow around the rotor where the prediction of air loads on rotor blades in different operational conditions and its relation to rotor structural dynamics is crucial for design purposes. Therefore, one of the most important challenges in wind turbine aerodynamics is to predict the forces on the blade accurately where the blade and wake are modeled by different approaches such as Blade Element Momentum (BEM) theory, vortex method and Computational Fluid Dynamics (CFD). In this paper, the application of vortex method for wind turbine aerodynamic performance is used. Different blade models such as lifting line and lifting surface with prescribed wake model are studied. The main purpose is to find the proper combination of blade and wake model influencing the aerodynamic loads as well as the computational time efficiency. The results of different approaches are compared with the GENUVP code. (See acknowledgements)
