BRIGE: Exploring New Parameters for Wind Turbine Array Design and Its Impact on Extracted Energy Availability

智力价值：一个公园的风力涡轮机（WT）的数量通常被限制在一个固定的、有限的地理区域内。“桥梁”项目是一项风洞实验研究，旨在测试可能影响风力涡轮机提取能力的新参数，从而为风力涡轮机阵列设计提供新的见解。风洞实验将在波特兰州立大学最新的最先进的风洞设施中进行。获得的数据将用于解决各种配置的以下问题：(i)测试涡轮高度、转速、间距、叶尖速比等参数以及几何布置，了解其对功率提取的影响；（ii）使用层析粒子图像测速（Tomo-PIV）在选定的测试配置下测量WT阵列风洞模型的高分辨率速度图，并更深入地了解这些。（iii）采用适当正交分解（POD）数据分析技术观察流动结构，更重要的是识别含能模态。研究结果将为设计最佳小波变换阵列提供工具，带来经济影响，并可能帮助计算机建模者模拟此类阵列。更广泛的影响：计划中的研究将提高从大气环境中提取风能的适用性、效率和对长期可持续性的理解。该项目还将有几个外联组成部分，包括：(i)暴露的博士生国际经验在奥斯陆,挪威(挪威国防研究机构)、(2)与一个高中在波特兰(格拉德斯通中学),具有可持续发展背景下,提高他们的意识在风能领域和保持学生动机在干细胞领域,(3)从波多黎各招募本科生参加暑期项目,成为他们的良师益友学术职业领域的能源和可持续性,以及（iv）在已经到位的MESA日中聘请本科生和研究生。

Intellectual Merit: The number of wind turbines (WT) in a park is usually restricted to a fixed, limited geographical area. This BRIGE project is a wind tunnel experimental study to test new possible parameters, which can impact the extracting capabilities of the wind turbine, thus providing new insight in wind turbine array design. The wind tunnel experiments will be carried out at the new state-of-the-art wind tunnel facility at Portland State University. The obtained data will be used to address the following issues for the various configurations: (i) test parameters such as turbine height, rotation, spacing and tip-speed ratio as well as geometrical arrangement to understand its impact on the power extraction, (ii) use Tomographic Particle Image Velocimetry (Tomo-PIV) to measure high-resolution velocity maps in wind tunnel models of WT arrays under the selected tested configurations and understand these more in depth, and (iii) employ Proper Orthogonal Decomposition (POD) data analysis technique to observe the flow structures and more importantly to identify the energy containing modes. Results will provide tools for designing optimal WT arrays, lead to economic impact and potentially aid computer modelers in simulating such arrays. Broader impacts: The planned research will advance the applicability, efficiency, and understanding of the long-term sustainability of wind energy extraction from the atmospheric environment. The project will also have several outreach components including: (i) expose a PhD student to an international experience in Oslo, Norway (with Norwegian Defense Research Establishment), (ii) work with a high school in Portland (Gladstone High School), which has a sustainability background, to raise their awareness in the area of wind energy and to keep students motivated in the area of STEM, (iii) recruit undergraduate students from Puerto Rico to attend summer programs and mentor them for academic careers in the fields of energy and sustainability, and (iv) involve hired undergraduates and graduate students in the already-in-place MESA day.
