Analytical and numerical evaluation for wind turbine aerodynamic characteristics

Energy lies at the core of ultramodern society, empowering everything from heating, lighting, computers, and food products to manufacturing and transport. A rising realization of the harmful climatic belongings of anthropogenic greenhouse gas emissions is boosting governmental pressure to alleviate or avoid CO2 discharge into the ambiance. Wind turbines are one of the most likely initial applications for renewable sources. The major challenge in the wind turbine field is designing a machine that performs efficiently, boosting its reliability and producing power. The necessity for computational and experimental proceedings for probing aeroelastic stability has increased with the increase in output power and the size of the turbines. Due to the complexity and high costs of experimental investigations, several modeling methods have been practical solutions for design and analysis objectives. In this context, this paper presents an evaluation study for the aerodynamic performance of wind turbines-by concentrating on analyses of aerodynamic workforces that act on the rotor, employing Blade Element Momentum (BEM) and with the usage of the Computational Fluid Dynamic (CFD) solver. The computed results show a reasonable agreement with the previous results found in the literature. This indicates that it is possible to predict the characteristics of wind turbines from analytical and numerical approaches with plausible reliability.
