The primary objective of the research in this proposal is to perform experiments on large scale wind turbines in a controlled environment and apply laser based optical flow measurement techniques such as flow visualization, laser Doppler velocimetry, and particle image velocimetry (PIV) to make detailed measurements of the velocity fields developed around the wind turbine blades. Experimental studies of wind turbine aerodynamics have the potential to improve the operation and efficiency of turbines while reducing costs and decreasing noise. As the wind resource is variable turbines operate over a large range of dynamic operating conditions. 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 velocity and acoustic data will be collected from a wind turbine under various operating conditions in controlled conditions in order to understand the behaviour of the flow, provide high quality validation data for model development and computational fluid dynamic (CFD) simulations of the flow and reliably quantify the above effects for inclusion in new tools for design.

本提案研究的主要目标是在受控环境中对大型风力涡轮机进行实验，并应用基于激光的光流测量技术，例如流可视化、激光多普勒测速和粒子图像测速（PIV），对风力涡轮机叶片周围形成的速度场进行详细测量。风力涡轮机空气动力学的实验研究有可能提高涡轮机的运行和效率，同时降低成本和噪音。由于风资源是可变涡轮机，因此可以在大范围的动态运行条件下运行。由于涡轮机本身的规模，在实际条件下以及可能对建模、验证和设计有用的规模上对涡轮机性能的研究并不常见。在该提案中，将从受控条件下的各种运行条件下的风力涡轮机收集速度和声学数据，以便了解流动的行为，为模型开发和流动的计算流体动力学（CFD）模拟提供高质量的验证数据，并可靠地量化上述影响以纳入新的设计工具中。
