GE using Large Eddy Simulation on Sandia’s Red Mesa to lay groundwork for quieter wind turbine blades with better power yield

Transition of flow to turbulence on a wind-turbine airfoil; isosurfaces of vorticity from a Large Eddy Simulation (LES). A 1 decibel quieter rotor design would result in a 2% increase in annual energy yield per turbine. Aeroacoustic noise is more difficult to mitigate, and is the dominant noise source on modern wind turbines.
