Energy Optimization of Savonius Vertical Axis Wind Turbine

This paper reports a wind-powered water pumping system implemented in rural side of Pakistan. The design methodology presented in this paper shall enhance the efficiency of the existing Savonius turbine’s performance by modifying it aerodynamically. Blades with different twist angles are designed in Solid Edge and analyzed using computational fluid dynamics(CFD) with ANSYS FLUENT software. Static and rotational analyses are performed to get optimized twist angle and results are highlighted. The performances of the turbine in both static and rotational analyses are compared.
