Design and Analysis of Vertical Axis Wind Turbine Blades for Street Lighting

With a view to harnessing wind energy in small application, a design of a vertical axis Savonius ? Darrieus integrated Wind Turbine is proposed to be mounted on a Streetlight pole. Important aspects about street lighting and wind data are discussed. The blade geometry (Troposkein shape) for the Darrieus rotor is approximated by an iterative method. The entire Design process is performed for two materials: Aluminum Alloy and E- glass Fiber. The aerodynamic forces are calculated on Darrieus blade and Savonius rotors stress analysis is performed on them. A computational fluid dynamics (CFD) tool (ANSYS Fluent) is used on Savonius blade for aerodynamic analysis. ANSYS Static Structural software is used for stress analysis.
