This paper concentrates on a new configuration for a wind turbine, named KIONAS.\nThe main purpose is to determine the performance and aerodynamic behavior of KIONAS, which\nis a vertical axis wind turbine with a stator over the rotor and a special feature in that it can consist\nof several stages. Notably, the stator is shaped in such a way that it increases the velocity of the air\nimpacting the rotor blades. Moreover, each stage�s performance can be increased with the increase of\nthe total number of stages. The effects of wind velocity, the various numbers of inclined rotor blades,\nthe rotor diameter, the stator�s shape and the number of stages on the performance of KIONAS\nwere studied. A FORTRAN code was developed in order to predict the power in several cases by\nsolving the equations of continuity and momentum. Subsequently, further knowledge on the flow\nfield was obtained by using a commercial Computational Fluid Dynamics code. Based on the results,\nit can be concluded that higher wind velocities and a greater number of blades produce more power.\nFurthermore, higher performance was found for a stator with curved guide vanes and for a KIONAS\nconfiguration with more stages.
