Document from the year 2011 in the subject Engineering - System Science, language: English, abstract: A wind turbine is a device that extracts kinetic energy of the wind and converts it into useful energy. The power produced by a wind turbine depends on the interaction between the wind turbine rotor and the wind. Thus, wind turbine aerodynamics is an important field of study for designing a blade and analyzing the aerodynamic performance of the rotor. A number of scientists have derived various methods for aerodynamic analysis of wind turbine rotors. These methods are presented here.
