Performance Predictions of VAWTs With NLF Airfoil Blades

Journal of Solar Energy Engineering, 1997
The successful design of an efficient Vertical Axis Wind Turbine (VAWT) can be obtained only when appropriate airfoil sections have been selected. Most VAWTs currently operating worldwide use blades of symmetrical NACA airfoil series. As these blades were designed for aviation applications, Sandia National Laboratories developed a family of airfoils ...

Theoretical aerodynamic methods for VAWT analysis

Proceedings of the 24th Intersociety Energy Conversion Engineering Conference, 2003
The peculiarities of vertical-axis wind turbines (VAWTs), such as simple blade building and the absence of an orientation system, are studied. A comparison is made of three theoretical methods quantified by means of an overall parameter as the average coefficient of power.

A new type of VAWT and blade optimization

International Technology and Innovation Conference 2009 (ITIC 2009), 2009
In this paper, the reason is analyzed that the vertical axis wind turbine (VAWT) is always with low efficiency, on the basis that a new type of VAWT with windshield is proposed (WSVAWT). The geometry characteristic of windshield has great influence on aerodynamic performance. Based on Bezier function, by introducing two parameters, i.e.
