Simulation of a wind turbine wake II
Simulation of a turbulent and meandering wake behind a wind turbine (WT).
The airflow around two WTs (rotor diameter 66m, hub height 65m) was simulated. The second WT is placed four rotor diameters behind the first WT and operates in its wake.

The simulations were undertaken with ANSYS FLUENT using the LES technique for turbulence modelling. The simulated geometry of the WTs includes tower, nacelle, rotating hub and blades.
The movie shows contours of velocity magnitude ranging from 2m/s (blue) to 16m/s (red) in a vertical cut through the center of the WTs. White patches indicate areas of velocity magnitude below 2m/s.
