Abstract:
In order to accurately model large, advanced and efficient wind turbines, more reliable and realistic aerodynamic simulation tools are necessary. Most of the available codes are based on the blade element momentum theory. These codes are fast but not well suited to properly describe the physics of wind turbines. On the other hand, by using computational fluid-dynamics codes, in which full Navier-Stokes equations are implemented, a strong expertise and a lot of computer time to perform analyses are required. A code, based on a generalized form of Prandtl’s lifting line in combination with a free wake vortex wake has been developed at Energy research Centre of Netherlands. In the present work, the development of this new code is presented, together with the results coming from numerical-experimental comparisons. The final part of the work is dedicated to the analysis of innovative configurations like winglets and curved blades.
