Wind turbines generate a certain amount of noise when generating electricity. In modern wind turbines, manufacturers have succeeded in reducing almost all mechanical noise and are now working hard to reduce aerodynamic noise from the rotating blades.
Noise is an important competitive factor, especially in densely populated areas. Some consider wind turbines to be unsightly in the landscape, but as larger wind turbines gradually replace older, smaller wind turbines, the actual number of wind turbine will decrease, while their generating capacity will increase. When installing many wind turbines in an area, it is important that they be acceptable to the people.
This could be accomplished by people living near the turbines owning a portion of the project and sharing in there venues. Additionally, noise and visual impacts will become less significant in the future as more wind turbines are installed off shore.
About the Book
Aerodynamics of Wind Turbines is an established and essential text that presents fundamental solutions for efficient wind turbine design. Now in its second edition, the book has been fully updated and significantly expanded to reflect advances in technology, rotor aerodynamics, and the structural response of wind turbines.
Topics covered include increased mass flow through turbine, performance at low and high wind speeds, evaluation of extreme conditions under which turbines perform, and theories for calculating turbine life. Classical blade element momentum methods are also covered, as are eigenmodes and the dynamic behavior of turbines.
New material includes an explanation of the effects of dynamics and how this can be modeled with the aeroelastic codes that are widely used in modern wind turbine design and validation. In addition, there is a significantly updated description of how to calculate the vibration of the entire structure as well as the time-varying loads.
This book is an essential reference for engineering students and others with a professional or academic interest in the physics and technology behind horizontal axis wind turbines.
