Aerodynamic performance prediction of Darrieus-type wind turbines
Journal Title: INCAS BULLETIN - Year 2010, Vol 2, Issue 2
Abstract
The prediction of Darrieus wind turbine aerodynamic performances provides the necessary design and operational data base related to the wind potential. In this sense it provides the type of turbine suitable to the area where it is to be installed. Two calculation methods are analyzed for a rotor with straight blades. The first one is a global method that allows an assessment of the turbine nominal power by a brief calculation. This method leads to an overestimation of performances. The second is the calculation method of the gust factor and momentum which deals with the pale as being composed of different elements that don’t influence each other. This method, developed based on the theory of the turbine blades, leads to values close to the statistical data obtained experimentally. The values obtained by the calculation method of gust factor - momentum led to the concept of a Darrieus turbine, which will be tested for different wind values in the INCAS subsonic wind tunnel.
