Performance Investigation of Vertical Axis Wind Turbine with Savonius Rotor using Computational Fluid Dynamics (CFD)

The quest of clean and sustainable energy has grown rapidly all over the world in recent years. Among renewable resources available, wind is considered one reliable, environmentally friendly, green fastest-growing source electricity generation. This generation accomplished through turbines. However, efficiency these turbines still very limited unsatisfactory. primary goal this study to evaluate performance a Savonius rotor turbine terms aerodynamic characteristics, including torque, torque coefficient, power coefficient. design blades varied its effects observed. simulation models are developed using modeling software known as Solidworks 2021 then generated into Ansys Design Modeler R1 define fluid domain. In total, three distinct modelled while varying diameter height rotor. performed FLUENT R21. A constant speed value 9.2 m/s been used throughout simulation. was carried out transient time flow with upstream speed. results have shown that coefficient increases TSR highest consensually obtained at almost unity (0.9) TSR. Comparing models, Model 2 generates followed by 3 1, respectively. power, nearly similar conclusion drawn.
