Abstract
Based on the morphological characteristics of wind turbine blade leading-edge erosion at different stages observed in actual wind farms, this study investigates the effects of leading-edge erosion morphology on the aerodynamic performance of wind turbine airfoils. The S809 airfoil was geometrically modified to simulate erosion features, and the Reynolds-Averaged Navier-Stokes (RANS) equations were solved using the SST k-ω turbulence model. The lift/drag coefficients and flow field characteristics were systematically analyzed. Results indicate that erosion morphologies characterized by pitting and minor cavities exhibit negligible impacts on the lift and drag coefficients of the airfoil.
