Abstract

The straight-bladed Darrieus type vertical axis wind turbine (SB-VAWT) has received considerableÿattention due to relatively high efficency of wind energy and simple blade design. Slection of airfoil is crucial for aerodynamic characateristics of SB-VAWT. A numerical investigation into performance of SB-VAWTs is carried out with several symmetric airfoils as well as asymmetric airfoils. The simulation method is through solving unsteady compressible RANS equations and turbulence model. The numerical results indicate, the thinner airfoil contributes to higher power coefficient peak, but leads to poorer self-startup performance. The asymmetric airfoil has advantages over symmetric one in improving aerodynamic performance. The different setup configurations of asymmetric airfoil NACA 4415 is also considered, which shows the concave-in configuration is more beneficial to improve power coefficient peak.
