Correlation of amplitude modulation to inflow characteristics

  author={Helge Aagaard Madsen and Franck Bertagnolio and Andreas C. Fischer and Christian Bak},
Amplitude modulation (AM) of noise from wind turbines and its more extreme version named “other amplitude modulation” OAM have been investigated intensively during the last few years due to the additional annoyance impact this type of noise has compared to broad band noise. In a recent published research by RenewableUK the hypothesis has been that one of the causes of OAM is transient stall on the blade due to non uniform inflow such as shear. Part of the RenewableUK research work was a… CONTINUE READING
