Review Paper of Savonius Vertical Axis Wind Turbine Rotor Blade
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2015, Vol 5, Issue 2
Abstract
This paper involves study of Savonius Vertical Axis Wind Turbine (SVAWT) blades. In past few years more research works are carried out to increase efficiency of Vertical Axis Wind Turbine. Review of all these papers shows that the experiments are conducted only on semi cylindrical bucket shape blades, twisted blades, blades with end flap edges and blades having frames with cavity vanes, for two blades, three blades and four bladed Savonius Vertical Axis Wind Turbine(SVAWT) to increase performance. They also conducted experiments by providing curtains or flow guide to the rotor, increasing in the stages of rotor and combining both Savonius and Darrieus rotor (i.e. hybrid rotors) to increase the efficiency of rotor. Research work or experiments on semi cylindrical bucket rotor blade edges, having extrusion or leading edges with different angles are not carried out. Development of these designs includes a multidisciplinary design optimization approach for optimizing the Vertical Axis Wind Turbine blade, considering both structural and fluid flow performance requirements. Weighted Property Method, Cost Property Method, limits Property Methods are used for Selection of suitable material. ANSYS and Computational Fluid Dynamics are used for structural analysis and fluid flow performance of newly designed blade.
