| Summary: | One of the most important factors for cost-effective SB-VAWT product is the selection of an appropriate airfoil to achieve desired aerodynamic performance and to optimise the overall dimensions of the SB-VAWT. Design changes related to airfoil also have the potential for increasing the cost effectiveness of SB-VAWTs. This research aims to perform a detailed performance analysis on a series of low Reynolds number (RN) airfoils selected to enhance the performance of smaller capacity fixed-pitch SB-VAWT. Three low RN airfoils have been selected as candidates for the blades of a smaller-capacity SB-VAWT. The research compares their performances with that of a conventionally used symmetric NACA 0015 airfoil. It was found that all candidate low RN airfoils produced higher torque than the NACA 0015 at lower tip speed ratios. © 2012 Taylor and Francis Group, LLC. |
