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正在全球增长。 像许多能源技术一样，并非没有诸如能源和可靠性成本之类的关注点。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了很多年。 在这些地区，这些行业雇用了许多工程师和研究人员。 在加拿大内部，在可再生能源技术（尤其是风能）中，当前有可能缺乏合格人员的短缺。 ***这项研究的总体目标是通过创新的工具和技术来推进风力涡轮空气动力学的知识，最终有助于提高的可靠性和降低风能的成本。 ***这项研究集中于通过涡轮空气动力学测量和建模以及动态翼型空气动力学测量方法来改善旋转涡轮叶片周围流动的理解。这些详细的测量将通过基于创新激光的光流量测量技术（例如流动可视化，激光多普勒速度计和粒子图像速率（PIV））进行。 ***研究涡轮在现实条件下的性能以及可能对建模，验证和设计有用的规模研究，这是由于涡轮机身的规模而不常见的。在此提案中，将在大型风能设施中的各种操作条件下在各种操作条件下从风力涡轮机中收集数据，以了解流动的行为，提供验证数据以建模流量，并可靠地量化上述效果，以纳入新的工具中的设计工具。 由于所研究的涡轮机的规模，在此提案中接受培训的研究人员将有一个独特的机会获得对未来行业或学术机会重要的高级技能。 行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绩效模型。 行业还将受益于研究人员在该计划中开发的知识和技能。 ***最近一直关注加拿大风能开发，训练有素的风能背景的研究人员将影响加拿大能源行业的投资和发展。 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。
