ABSTRACT
This study focuses on optimizing the NACA-0015 aerofoil that would be easily used in wind turbines on a vertical axis. The profile changes considered are the amalgam of both the inward dimple and the Gurney flap on the NACA-0015's higher pressure surface. For optimization, a total of seven forms of modifications were considered. Data generated from the aerofoil profile analysis of computational fluid dynamics are used for optimization. To ensure that the optimization is decisive, CFD simulations are validated against existing experimental results.
