A study on aerodynamic properties of some NACA profiles used on wind turbine blades

Abstract

In this present study, fourteen different Re numbers, four different NACA profiles and lifting and drifting coefficients have been found by Snack 2.0 Computer program. By those determined values appropriate sliding rates of wind turbine blade profiles for each angle of attack have been calculated. For the determined four different NACA profiles correlations between the sliding numbers and the angle of attack, between the most convenient angle of attack and fourteen different Re number and lifting numbers and angle of attack have been revealed and depicted in a chart form. In addition, for the fourteen various Re numbers correlation between the lifting and drifting rates has been found out. © 2007 Asian Network for Scientific Information.
