This paper presents a comprehensive analysis of an airfoil in wind turbine applications. This study mainly focuses on exploring the aerodynamic behaviour of the airfoil at different angles of attack conditions. The K-ω SST turbulence model is used for this study. The simulations are performed at different Reynolds numbers, and velocity contours are observed to gain insights into the flow characters. Furthermore, the lift and drag coefficients are calculated, providing important information about the airfoil’s performance across a range of attack settings. Particularly at a high angle of attack, flow time analysis of the aerodynamic coefficients is also investigated. The lift and drag coefficients are periodic over time at high angle of attack with an increased number of cycles within a given period as the Reynolds number increases. The study also investigates how vortex generators affect an airfoil’s aerodynamic characteristics. The findings of this study advance our understanding of airfoil behaviour in applications for wind turbines and offer helpful data for design optimization and performance enhancement.
