Vertical Axis Wind Turbine Acoustics

Author: Charlie PearsonPublication: Cambridge UniversityYear Published: 2013 Increasing awareness of the issues of climate change and sustainable energy use has led to growing levels of interest in small-scale, decentralised power generation. Small-scale wind power has seen signi_cant growth in the last ten years, partly due to the political support for renewable energy and the introduction…

Reduction of the Generated Aero-Acoustics Noise of a Vertical Axis Wind Turbine Using CFD (Computational Fluid Dynamics) Techniques

Author: H. MohamedPublication: EnergyYear Published: 2016 Noise pollution from wind turbines is an important public health issue, and strict regulations regarding noise levels for nearby residents to a wind farm is a necessity. The fact that more turbines equals higher noise levels constitutes a problem, an expansion of turbines is needed but the nearby residents…

Noise Propagation from a Vertical Axis Wind Turbine

Author: Erik Mollerstrom, Sebastian Larsson, Fredric Ottermo, Jonny Hylander and Lars BaathPublication: Inter-noiseYear Published: 2014 Initial noise measurements were performed on a 200kW vertical axis wind turbine (VAWT) and results were compared to that of a Vestas V27, a similar size horizontal axis wind turbine (HAWT). Multiple recording units were placed in line downwind of…

Noise Emission of a 200 kW Vertical Axis Wind Turbine

Author: Erik Mollerstrom, Fredric Ottermo, Jonny Hylander and Hans BernhoffPublication: EnergiesYear Published: 2015 The noise emission from a vertical axis wind turbine (VAWT) has been investigated. A noise measurement campaign on a 200 kW straight-bladed VAWT has been conducted, and the result has been compared to a semi-empirical model for turbulent-boundary-layer trailing edge (TBL-TE) noise.…

Evaluating the Impact of Wind Turbine Noise on Health-Related Quality of Life

Author: Daniel Shepherd, David McBride, David Welch, Kim Dirks, Erin HillPublication: Noise HealthYear Published: 2011 We report a cross-sectional study comparing the health-related quality of life (HRQOL) of individuals residing in the proximity of a wind farm to those residing in a demographically matched area sufficiently displaced from wind turbines. The study employed a nonequivalent…

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

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…
