Large-eddy simulation of turbine wake interactions in a large wind farm Share Share

When wind-turbines are set up in large wind farms, down-wind turbines are driven by the turbulent wake of those up-wind, leading to significant reductions in their performance.

 

Using numerical simulations, Chang-Hung Chen studied the flow characteristics within a large wind farm, focusing in particular on the Horns Rev offshore wind farm in Denmark.

 

His results revealed that losses in performance for down-wind turbines are reduced when overall atmospheric turbulence increases and that small changes in wind direction can lead to large fluctuations in power production. Furthermore, he proposed an improved and more robust circular wind farm layout.
