SWEPT2

SWEPT 2项目旨在开发一种用于风力涡轮机尾流和尾流相互作用建模的复杂工具。众所周知，目前的尾流模型是不够的，特别是对于大型海上风电场的应用，并导致风电场设计具有大于预期的尾流损失。改进的尾流模型对于改进风电场设计和提高发电量至关重要。尾流模型的验证至关重要，但很难在全尺寸下进行。因此，萨里大学的EnFlo实验室将使用其专业风洞设施，EnFlo分层流风洞，在一系列风流条件下对模型风力涡轮机尾流、尾流-尾流和尾流-涡轮机相互作用进行测量。该风洞是全球为数不多的此类设施之一，能够模拟稳定和不稳定的大气风流。大气稳定度对涡轮机尾流有很大的影响，实验室的受控环境允许进行比现场测量更详细的研究。一个将补充和提供对另一个的检查。两者都将为该联盟中计算预测工具的开发提供相关物理和测试案例数据的见解。

The SWEPT2 project aims to develop a sophisticated tool for modelling of wind turbine wakes and wake interactions. It iswell known that present wake models are inadequate, especially for application to large offshore wind farms, and have ledto wind farm designs with larger than expected wake losses. Improved wake models are essential for improved wind farmdesigns with improved energy yield. Validation of wake models is critical but difficult to undertake at full scale. Therefore,the EnFlo Laboratory at the University of Surrey will use its specialist wind tunnel facility, the EnFlo stratified flow windtunnel, to make measurements on model wind turbines wakes, wake-wake and wake-turbine interactions, in a range ofwind flow conditions. The wind tunnel, one of the very few such facilities globally, is able to simulate stable and unstableatmospheric wind flow. Atmospheric stability has a large affect on turbine wakes, and the controlled environment of thelaboratory allows more detailed studies than can be obtained from field measurements. One will complement and providechecks on the other. Both will provide insight into the relevant physics and test-case data for the development ofcomputational prediction tools in the consortium.
