Year: 2025

Type: article

Abstract: : The icing of horizontal-axis wind turbine blades in cold regions significantly alters their power output and aerodynamic performance. To address this issue, an air film heating method was implemented for anti-icing. The NACA63(2)-215 airfoil was chosen as the subject of study. Numerical simulations of frost formation were performed on both the modified airfoil with leading-edge film holes and the original airfoil, using FLUENT and FENSAP-ICE software. Ice formation characteristics were analyzed for both airfoils under varying inflow wind speeds and liquid water content. The study reveals that the holed airfoil demonstrates effective anti-/de-icing performance compared to the original airfoil across various angles of attack, although the location of ice suppression shifts with increasing angle. At low liquid water content, ice accumulation at the jet-induced air film is notably reduced compared to the original airfoil. Overall results indicate that air film heating can effectively reduce icing on the leading edge when the icing duration is under 3 hours and liquid water content is below 0.25g/m 3 .
