Energy produced from wind turbines is growing worldwide. Like many energy technologies it is not without concerns such as cost of energy and reliability. Wind energy projects, while relatively new in Canada, have been established in Europe and the US for many years. In these regions, a significant number of engineers and researchers are employed in these industries. Within Canada, there is a current and foreseeable shortage of qualified personnel in renewable energy technologies, wind energy in particular. *** The overarching goal of this research is to advance the state of knowledge of wind turbine aerodynamics with innovative tools and techniques, ultimately contributing to the increased reliability and cost reduction of wind energy. *** This research concentrates on improving the understanding of the flow around rotating turbine blades through turbine aerodynamic measurement and modeling, and dynamic airfoil aerodynamic measurements. These detailed measurements around wind turbine blades will be made with innovative laser based optical flow measurement techniques such as flow visualization, laser Doppler velocimetry, and particle image velocimetry (PIV). *** Studies of turbine performance over realistic conditions, and at a scale that may be useful for modeling, validation and design are not common due to the scale of turbines themselves. In this proposal data will be collected from a wind turbine under various operating conditions in controlled conditions in a large wind facility in order to understand the behaviour of the flow, provide validation data for modeling of the flow and reliably quantify the above effects for inclusion in new tools for design.*** Detailed, high quality research measurements acquired during the research proposed will have a significant impact on the research community since measurements at the large scale are complex, costly and challenging to obtain. Due to the scale of the turbines studied, researchers trained in this proposal will have a unique opportunity to obtain advanced skills important for future industry or academic opportunities. Industry will benefit from the results obtained in this program since it will allow development of turbine performance models. Industry will also benefit from the knowledge and skills developed by the researchers in this program. *** There has been a recent focus on wind energy development in Canada and trained researchers with an excellent background in wind energy will make an impact on the investment and development of this energy industry in Canada. The research described here will elevate Canada's standing in the wind energy industry and international research community.

风力涡轮机产生的能源在全球范围内都在增长。与许多能源技术一样，它也不是没有能源成本和可靠性等方面的担忧。风能项目虽然在加拿大相对较新，但在欧洲和美国已经建立多年。在这些地区，大量的工程师和研究人员受雇于这些行业。在加拿大国内，目前和可以预见的是，可再生能源技术方面的合格人才短缺，特别是风能。*这项研究的首要目标是用创新的工具和技术提高风力机空气动力学的知识水平，最终为提高风能的可靠性和降低成本做出贡献。*本研究致力于通过涡轮气动测量和建模以及动态翼型气动测量来提高对旋转涡轮叶片周围流动的了解。这些围绕风力涡轮机叶片的详细测量将使用创新的基于激光的光学流动测量技术，如流动可视化、激光多普勒测速和粒子图像测速(PIV)。*由于涡轮机本身的规模，研究涡轮机在实际条件下的性能以及在可能对建模、验证和设计有用的尺度上的研究并不常见。在本提案中，将在大型风力设施的受控条件下从风力涡轮机收集各种运行条件下的数据，以了解流动的行为，为流动建模提供验证数据，并可靠地量化上述影响，以便纳入新的设计工具。*在拟议研究期间获得的详细、高质量的研究测量将对研究界产生重大影响，因为大规模测量是复杂、昂贵和具有挑战性的。由于所研究的涡轮机的规模，在这项建议中接受培训的研究人员将有一个独特的机会获得对未来的行业或学术机会至关重要的高级技能。工业将从该计划中获得的结果中受益，因为它将允许开发涡轮机性能模型。该行业还将受益于该项目研究人员开发的知识和技能。*加拿大最近将重点放在风能发展上，训练有素、具有良好风能背景的研究人员将对加拿大这一能源行业的投资和发展产生影响。这里描述的研究将提升加拿大在风能行业和国际研究界的地位。
