An airfoil optimization technique for wind turbines ...

01-10-2012  Airfoils created for airplanes are occasionally used in wind turbines, even though the design criteria are not the same for both cases. For instance, in wind turbines the airfoil can be used at a higher angle of attack, sometimes even achieving stall, and the most important parameter is the lift-to-drag ratio.

Airfoil Design for a Vertical Axis Wind Turbine Leonardo ...

27-06-2016  The Darrieus wind turbine is a type of Vertical Axis Wind Turbine patented in 1931 by George Jean Marie Darrieus, a French aeronautical engineering. A specific aerodynamic phenomenon was highlighted in this research, namely flow curvature. This phenomenon arises as a VAWT airfoil not only has a translational motion, but also a rotational one.

Genetic Algorithms in Wind Turbine Airfoil Design

One key element in the aerodynamic design of wind turbines is the use of specially tailored airfoils to increase the ratio of energy capture to the loading and thereby to reduce cost of energy. This work is focused on the design of a wind turbine airfoil by using numerical optimization. Firstly, the optimization approach is presented; a genetic algorithm is used, coupled with RFOIL solver and a composite
