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.
