Abstract

In the present study, two types of add-on flaps tangential to the camber line of small horizontal axis wind turbine blade are introduced and their performances on the production power are investigated. The wind turbine of Berlin University (TU-BERT) is used as the base turbine and the flaps' length, angle, and their locations on the blade are selected as geometric variables. The generated turbine power is calculated numerically by solving three-dimensional Navier–Stokes equations with a finite volume method using SST k–ω turbulence model. After parametric study considering the effects of flap geometric variables on the production power, a proper arrangement of flaps is proposed. Results show that the straight and curved flaps with the best flap arrangement are able to increase the power coefficient of the wind turbine by 5.8% and 10.5%, respectively, at the rated wind speed of 5.5 m/s and tip speed ratio of 4.5.

一种用于提高小型水平轴风力发电机性能的新型附加襟翼

本文介绍了两种与小水平轴风力机叶片弧度线相切的附加襟翼，并研究了它们对产生功率的影响。以柏林大学（TU-BERT）风力机为基础，选取襟翼的长度、角度及其在叶片上的位置作为几何变量。采用SST k -ω湍流模型，采用有限体积法求解三维Navier-Stokes方程，对涡轮发电功率进行了数值计算。通过参数化研究，考虑了襟翼几何变量对生产功率的影响，提出了合理的襟翼布置方式。结果表明，在额定风速为5.5 m/s、叶尖速比为4.5的情况下，采用最佳襟翼布置方式的直襟翼和曲襟翼可使风力机的功率系数分别提高5.8%和10.5%。

期刊介绍： Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
