NAFNoise

NAFNoise, which stands for NREL AirFoil Noise, is a program that predicts the noise of any airfoil shape for five different types of noise sources.

The five noise sources NAFNoise predicts are:

  • Turbulent boundary layer trailing-edge noise
  • Separated flow noise
  • Laminar boundary layer vortex-shedding noise
  • Trailing-edge bluntness noise
  • Turbulent inflow noise.

The models in the program are based on the work of others and research performed at NREL.

This software was developed by Pat Moriarty of NREL.

Note: NREL is not furthering the development this software. The links below are provided for archival purposes only.
