Aeroacoustics Prediction of a Vertical Axis Wind Turbine Using Large Eddy Simulation and Acoustic Analogy

Acoustics, Environmental Impacts

Author: Masoud Ghasemian, Amir NejatPublication: EnergyYear Published: 2015 Operating wind turbines generate tonal and broadband noises affecting the living environment adversely; especially small wind turbines located in the vicinity of human living places. Therefore, it is important to determine the level of noise pollution of such type of wind turbine installation. The current study carries…

Aeroacoustics of Darrieus Wind Turbine

Acoustics, Environmental Impacts

Author: Johannes Weber, Stefan Becker, Christoph Scheit, Jens Grabinger and Manfred KaltenbacherYear Published: 2005 The objective of this paper is to validate two different numerical methods for noise prediction of the H-Darrieus wind turbine using a complementary approach consisting of experimental measurements and numerical simulations. The acoustic measurements of a model scale rotor were performed…
