NAFNoise

A Program for Calculating 2-D Airfoil Noise

by Pat Moriarty
National Wind Technology Center

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: turbulent boundary layer trailing-edge noise, separated flow noise, laminar boundary layer vortex-shedding noise, trailing-edge bluntness noise, and turbulent inflow noise. The models in the program are based are based on the work of others and research performed at NREL.
