APPLICATION OF CONCRETE BLADES ON A NEW TYPE OF VERTICAL AXIS WIND TURBINE

Abstract eng:
The research focuses on developing a new type of vertical axis wind power generator, in which fan-shaped up-structure with floating foundation on water is used to catch the wind and the entire energy of the motion of whole system floating on the liquid is used to generate the electricity. The floating support structure carries the self-weight of concrete blades to avoid large stress exerting on the rotating axes. This idea has completely changed the concept of traditional wind power production and has a great potential to make the wind power generation economic, efficient and sustainable. The generator can be used for sustainable energy development. Based on the experiments and aerodynamic analysis, a quantitative comparison with horizontal axis wind turbine indicates a clear advantage of this new type of Vertical Axis Wind Turbine (VAWT) in economic and power generation efficiency. Moreover, the optimum configuration of the system will be discussed.
