Vertical Axis Wind Turbine - an overview | ScienceDirect ...

Vertical axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically. Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective. This is an advantage on sites where the wind direction is highly variable. VAWTs can utilise winds

CHAPTER 8 Development and analysis of vertical-axis

2014-5-10 · Vertical-axis wind turbines (VAWTs) have been demonstrated to be effective devices for extracting useful energy from the wind. VAWTs have been used to generate mechanical and electrical energy at a range of scales, from small-scale domestic applications through to large-scale electricity production for utilities. This chapter summarises the development of the main types of VAWT, including the Savonius, Darrieus and Giromill designs. A summary of the multiple-streamtube analysis of VAWTs is also provided to illustrate how the complex aerodynamics of these devices may be analysed using relatively straightforward techniques. Results from a double-multiple-streamtube analysis are used to illustrate the details of the performance of VAWTs in terms of turbine blade loads and rotor power output as a function of fundamental parameters such as tip speed ratio. The implications for VAWT
