Author: Marco D’ Ambrosio, Marco MedagliaPublication: Hogskolan HalmstadYear Published: 2010 In these Master Thesis a review of different type of vertical axis wind turbines (VAWT) and an preliminary investigation of a new kind of VAWT are presented. After an introduction about the historical background of wind power, the report deals with a more accurate analysis…
Author: J. Damota, I. Lamas, A. Couce, J. RodriguezPublication: J. Renewable Energy & Power QualityYear Published: 2015 This paper, based on the pursuit of scientific articles published and recorded in the last five years (2010-2014) patents on VAWT technology, gives an image of the current situation of the treated technology. From data extracted we know:The…

Author: FloWind CorporationPublication: Sandia National LaboratoriesYear Published: 1996 Under the auspices of the “Government/Industry Wind Technology Applications Project” [“Letter of Interest” (LOI) Number RC-1-11101], Flo Wind Corp. has successfully developed, tested, and delivered a high-energy rotor upgrade candidate for their 19-meter Vertical Axis Wind Turbine. The project included the demonstration of the innovative extended height-to-diameter…
Author: J. F. Banas, E. G. Kadlec, W. N. SullivanPublication: Sandia National LaboratoriesYear Published: 1975 This report suggests that the Darrieus vertical-axis wind turbine may be particularly well-suited for driving a synchronous generator in parallel with a synchronizing electrical power network. Aerodynamic characteristics of the Darrieus wind turbine can be such that no torque regulation…
Author: Jerbert Sutherland, Dale Berg, and Thomas AshwillPublication: Sandia National LaboratoriesYear Published: 2012 The study of Vertical-Axis Wind Turbine (VAWT) technology at Sandia National Laboratories started in the 1970’s and concluded in the 1990’s. These studies concentrated on the Darrieus configurations because of their high inherent efficiency, but other configurations (e.g., the Savonius turbine) were…
