Wind energy investigation of straight-bladed vertical axis wind turbine using computational analysis

Abstract

Vertical axis wind turbines received renewed attention for increasing offshore wind energy harvesting and in urban environments. This turbine reflects a specific type of technology that generates electricity from wind, which is renewable sources of energy. This research explores the effect of blade profile modifications on the VAWT aerofoil NACA0012 and NACA2415. Analysis of the lift/drag coefficient and calculation of the average torque/self-starting potential of NACA0012 and NACA2415 for NACA0012, as this is a significantly better measure of the power generated at different pitch angles and comparison of both profiles. The dataset is created using Computational Fluid Dynamics (CFD) simulations, which were performed in ANSYS-Fluent. Various parameters, such as the number, thickness, and angle of attack of the Reynolds no.were investigated. The aerodynamics of the wind turbine blade is shown to increase the optimized form of the modified aerofoil.
