The Influence of Two Flow Control Methods on the Anti-Wind Sand Erosion Wear of Airfoils

This chapter delves into the influence of two distinct flow control methods—leading-edge winglets and cylinders—on the anti-wind sand erosion wear of airfoils, crucial components of wind turbine blades. The study meticulously examines how these methods affect the aerodynamic performance and erosion resistance of airfoils, using the NACA0012 airfoil as a benchmark. Through advanced numerical simulations and experimental data, the research reveals that both leading-edge winglets and cylinders significantly enhance the aerodynamic efficiency and wear resistance of airfoils. Notably, the leading-edge cylinder method demonstrates superior protection against erosion and wear, particularly at various angles of attack. The comparative analysis highlights the leading-edge small wing's better aerodynamic performance and the leading-edge cylinder's enhanced erosion resistance, offering valuable insights for improving wind turbine durability and efficiency in sandy environments.
