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

智力优势：一个园区的风力涡轮机（WT）数量通常局限于一个固定的、有限的地理区域。 BRIGE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先进的新风洞设施中进行。 获得的数据将用于解决各种配置的以下问题：（i）测试参数，例如涡轮机高度、旋转、间距和叶尖速度比以及几何布置，以了解其对功率提取的影响，（ii）使用层析粒子图像测速法（Tomo-PIV）在选定的测试配置下测量WT阵列风洞模型中的高分辨率速度图，并更深入地了解这些，（iii）采用POD数据分析技术观察流场结构，更重要的是识别含能模态。 研究结果将提供工具，设计最佳的WT阵列，导致经济的影响，并可能帮助计算机建模模拟这样的阵列。 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，效率和长期可持续性的理解。该项目还将包括若干外联部分，包括：（i）让博士生在挪威奥斯陆体验国际经验（与挪威国防研究所合作），㈡与波特兰的一所高中合作（格莱斯顿高中），其中有一个可持续发展的背景，以提高他们在风能领域的认识，并保持学生在干领域的积极性，（iii）招募来自波多黎各的本科生参加暑期课程，并指导他们在能源和可持续性领域的学术生涯，以及（iv）让聘用的本科生和研究生参与已经到位的梅萨日。

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.
