Abstract
Urban areas lack the average wind speed needed to operate horizontal axis wind turbines (HAWT), so vertical axis wind turbines (VAWT) are in demand. Savonius (Drag) and Darrieus (Lift) types of vertical axis wind turbines are both used. The comparison of the coefficients of performance (COP) of Savonius and Darrieus types of vertical axis wind turbines is the main focus of the current study. ANSYS Fluent-Computational Fluid Dynamics (CFD) software is used to numerically analyse the aforementioned VAWTs. Both turbines' blade designs are selected to provide the best output possible given the available input. The wind turbines' output parameters are obtained separately and compared for the same input parameters. This comparison provides a basis for choosing the type of VAWT to be implemented according to the function.
