摘要

风力机叶片的设计是获得高效风力机的关键。在风能领域,为了获得成功的设计,必须了解影响风力机叶片的设计和参数。然而,大多数参数是相互依赖的,这使得风力涡轮机的设计成为一项具有挑战性的任务。本文采用QBlade软件对小型水平轴风力机的性能进行了分析和优化。该软件应用叶片单元动量理论(BEM)对风力涡轮机叶片进行研究,通过将叶片分为10个上升段来计算阻力和升力系数。对叶片的扭角和弦长进行了优化,以获得最佳性能。在各种翼型中,选择SG-6041翼型来构建叶片结构。计算得到的功率系数接近0.4,考虑到这是在平均风速10 m/s、叶片长度1 m条件下计算得到的功率系数,已经算是很高了。在所有结果都合乎逻辑、合理的情况下,证明该软件是可靠的。本文还对伊拉克不同地点的风特性进行了评价,以期找到伊拉克最优的有发展前景的地点。

An Investigation of Design and Simulation of Horizontal Axis Wind Turbine Using QBlade
Abstract The wind turbine blade design is important in obtaining an effective wind turbine. In the field of wind energy, it is essential to understand the design and parameters affecting the blades of the wind turbine in order to obtain a successful design. However, most of the parameters are dependent on each other and this makes the design of wind turbines a challenging task. This research paper used the QBlade software to analyze and optimize the behavior of the small horizontal axis wind turbine. The software applies the Blade Element Momentum Theory (BEM) to study the wind turbine blades by calculating the drag and lift coefficients which were achieved by dividing the blades into 10 ascending segments. The twist angle and chord length of the blade are optimized to get the highest performance. Among the various airfoil types, the SG-6041 airfoil type was selected to build the blade structure. The calculated power coefficient was almost 0.4, which is considered high given that it was calculated under 10 m/s average wind speed and 1-meter length blade conditions. Where all the results are logical and reasonable, the software is proven to be reliable. The paper also evaluates the wind characteristics in different locations in Iraq in order to find the most optimal promising locations in Iraq.
