A semi-analytical model for velocity profile at wind turbine wake using blade element momentum
The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. The pr...

متن کاملCFD Wake Modelling with a BEM Wind Turbine Sub-Model
Modelling of wind farms using computational fluid dynamics (CFD) resolving the flow field around each wind turbine’s blades on a moving computational grid is still too costly and time consuming in terms of computational capacity and effort. One strategy is to use sub-models for the wind turbines, and sub-grid models for turbulence production and dissipation to model the turbulent viscosity accu...
متن کاملWind Turbine Wake Characterization from Temporally Disjunct 3-D Measurements
Scanning LiDARs can be used to obtain three-dimensional wind measurements in and beyond the atmospheric surface layer. In this work, metrics characterizing wind turbine wakes are derived from LiDAR observations and from large-eddy simulation (LES) data, which are used to recreate the LiDAR scanning geometry. The metrics are calculated for two-dimensional planes in the vertical and cross-stream ...
