Experimental and Numerical Study on Modified Vertical Axis Wind Turbine

Abstract

Wind energy is very important in the development of sustainable energy with the growing focus on renewable energy; interest in design of wind turbines has also been expanding. In today's market, the horizontal axis turbine is the most common type in use; Experimental data of this research is to compare the CFD Analysis with the Experimental Data of hybrid Modified vertical axis wind turbine. The graphical data based on the parameters such as Velocity, Power Coefficient, Tip Speed Ratio Vs Power Coefficient and Wind Velocity Vs Power Coefficient, which are discussed in this research. The Savonius turbine (Lift Turbine) was attach with the Gorlov turbine (Drag driven turbine) for the self-starting of the hybrid-modified turbine. Here the design, construction and testing of vertical axis wind turbine with three blades, starting solely from low energy of the wind. The velocities such as 5, 7, 9 and 11 m/s are tested in CFD Analysis for checking from which maximum power can be extracted so it can be used in desert area.
