Distributed small scale renewable energy production systems such as building mounted wind turbines have the potential to play a significant role in electricity production. Solar energy is leading this revolution but requires a large footprint. Wind turbines are complementary to solar and can lead to more efficient electricity production in windy areas. Nevertheless, distributed small scale wind turbines have suffered in reputation because of inadequate placement in areas where there is no wind or on building roofs for which they were not designed for. In this project, a wind turbine enclosed in a diffuser, specifically designed for the roof of a building, is improved. Currently this turbine has a good power extraction efficiency but its effectiveness is limited as only a few operating parameters have been studied. In the current research project, two tasks will be tackled. In the first task, the diffuser intake will be analysed and optimized with respect to varying wind directions and closing vane guides. The blade geometry is a key parameter of any wind turbine. In the second task, an optimization approach will be developed to investigate different blade geometries and identify the blade characteristics that will lead to the highest energy extraction. This work will be performed as a collaboration between Prof. Paraschivoiu's research group at Concordia University and the industrial partner Le Groupe LML.

分布式的小规模可再生能源生产系统（例如建筑安装的风力涡轮机）有可能在电力生产中发挥重要作用。太阳能正在引领这场革命，但需要大量的占地面积。风力涡轮机是太阳能的互补，可以导致大风地区的发电效率更高。然而，由于在没有风或建筑屋顶上没有设计的区域的位置不足，因此在声誉中遭受了分布的小型风力涡轮机。在这个项目中，改善了专门为建筑物屋顶设计的扩散器中的风力涡轮机。目前，该涡轮机具有良好的功率提取效率，但由于仅研究了一些操作参数，因此其效率受到限制。在当前的研究项目中，将解决两个任务。在第一个任务中，将分析和优化扩散器的摄入量，并优化不同的风向和关闭叶片指南。刀片几何形状是任何风力涡轮机的关键参数。在第二个任务中，将开发一种优化方法来研究不同的叶片几何形状并确定将导致最高能量提取的叶片特性。这项工作将作为Concordia大学Paraschivoiu教授研究小组与工业合作伙伴LE Groupe LML之间的合作。
