Numerical Investigations on Aerodynamic Characteristics of Savonius Wind Turbine
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 4
Abstract
In This Paper Objective Is To Investigate The Aerodynamic Performance Of Savonius Wind Turbine. Wind Tunnel Investigation Was Carried Out To Find The Aerodynamic Characteristics Like, Drag Coefficient, Torque Coefficient, And Power Coefficient Of Three Blade Savonius Wind Turbine Rotor Models With And Without Overlap Ratio (Ratio Of Overlap Distance Between Two Adjacent Blades And Rotor Diameter ,Or = A/D) At Various Reynolds Numbers. Numerical Investigation Was Acarried Out To Find Those Aerodynamic Characteristics. For Numerical Investigation, Commercial Computational Fluid Dynamic (Cfd) Software Fluent Were Used. Afterwards Those Two Results Were Compared For Verification. The Results From The Experimental Part Of The Research Show A Significant Effect Of Overlap Ratio And Reynolds Number On The Improvement Of Aerodynamic Performance Of The Savonius Wind Turbine. At Higher Reynolds Number Turbine Model Without Overlap Ratio Gives Better Aerodynamic Coefficients And At Lower Reynolds Number Model With Moderate Overlap Ratio Gives Better Results.
