Abstract: A new methodology is initiated to design a wind turbine that can operate efficiently in low wind speed conditions. The scenario explained elaborately in this research paper have the blades designed to offer an efficient solution for low wind speed zones. The different forces and angles at specific locations on the blade are designed, tested and implemented. Computational fluid dynamics (CFD) is employed to forecast the performance of blades along with the visualisation of velocity; pressure and velocity streamline distribution around the blade when rotated at the proposed rpm. The aerodynamic performance of the blade coincides with the design requirements and is scrutinised for variable wind conditions. A six bladed wind turbine system is used as replacement for the conventional large diameter blades. The computational results indicate that the power output is obtained at 3.4 m/s whereas the experimental power output is obtained at 4.4 m/s.
