SWEPT2

SWEPT2项目旨在开发一种用于模拟风力涡轮机尾迹和尾迹相互作用的复杂工具。众所周知，现有的尾流模型不能很好地应用于大型海上风电场，导致风电场设计中的尾流损失大于预期。改进的尾流模型对于改进风电场设计和提高能量产量至关重要。尾流模型的验证是关键的，但很难全面进行。因此，萨里大学的EnFlo实验室将利用其专门的风洞设施EnFlo分层流风洞，在一系列风流条件下对模型风力涡轮机的尾迹、尾迹和尾迹与涡轮机的相互作用进行测量。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。大气稳定性对涡轮机尾迹有很大影响，实验室的受控环境允许进行比现场测量更详细的研究。其中一个将补充和提供另一个。两者都将为该联盟的计算预测工具的开发提供对相关物理和测试案例数据的洞察。

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.
