Methods for obtaining lift and drag coefficients for a wide range of Reynolds numbers and angles of attack for wind turbine applications
Keywords:
Wind Turbine, lift coefficient, drag coefficient, panel method, extension of angles of attackAbstract
In research of wind turbine design, often isnecessary to analyze the behavior of different typesof aerodynamic profiles on their blades. Of these,is necessary to know the coefficients of lift anddrag, but this data is not available for all the profileswanted to be used to analyze the turbines.In this paper will be explore an alternative forthe determination of these coefficients and isimplemented the methodology for generatingcurved profile data.
