AIRFOIL SELECTION FOR AERODYNAMIC PERFORMANCE CRITERION ON SMALL WIND TURBINES

Emanuela Sorina SOUCA, Cornel CIUPAN

Abstract


Performance optimization is one of the major concerns in wind turbines industry and especially for small wind turbines, which are mostly found in the urban areas. As we know, urban areas have a turbulent wind flow, frequent changes of wind flow direction and intensity, gusts and other obstacles. This paper focuses on studying the aerodynamic performance of different airfoils which are widely used on small wind turbines. The results obtained from airfoil analysis have shown that asymmetric profiles are suitable for small wind turbines, because they have the best aerodynamic lift drag ratio on a big range of attack angles.

Key words: small wind turbines, airfoil profile, aerodynamic performance, drag, lift.
