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.

分布式小规模可再生能源生产系统，如安装在建筑物上的风力涡轮机，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，但需要大量的足迹。风力涡轮机是太阳能的补充，可以在多风地区提高发电效率。然而，分布式小型风力涡轮机由于在没有风的区域或在它们未被设计用于的建筑物屋顶上的不适当放置而在声誉上受损。在该项目中，改进了专门为建筑物屋顶设计的封闭在扩散器中的风力涡轮机。目前，这种涡轮机具有良好的功率提取效率，但其有效性有限，因为仅研究了少数操作参数。在目前的研究项目中，将解决两个任务。在第一项任务中，将针对不同风向和关闭导叶对扩压器进气进行分析和优化。叶片几何形状是任何风力涡轮机的关键参数。在第二项任务中，将开发一种优化方法，以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。这项工作将由Concordia大学Paraschivoiu教授的研究小组和工业合作伙伴Le Groupe LML合作进行。
