CONTEXT

Understanding
of Wind turbine wake

Behind the turbine:
  • Tip vortex development
  • Breakdown of the vortices
  • Mixing with the Atmospheric Boundary Layer

Results in:
  • Top-hat to Gaussian velocity profiles
  • Wake expansion
  • Highly turbulent regions

Wind Turbine
Wake Effects

Production losses: 10-20% in offshore and 5-10% in onshore farms

Fatigue increase due to additional turbulence: 5-15% component fatigue life reduction

FarmShadow™ combines analytical wake models to enable rapid evaluation of a wind farm’s power output and/or Annual Energy Production (AEP)
