The icing on wind turbines reduces their aerodynamic performance and can cause other safety issues. Accordingly, in this paper, the de-icing characteristics of a turbine blade airfoil under different conditions are investigated using numerical simulation. findings indicate that when time is 10 s, peak ice thickness leading edge surface decreases from 0.28 mm to 0.068 0.77 0.45 at low (5 m/s) high (15 speeds, respectively. This due fact melting rate much greater than while increases speeds. When 20 accretion completely melted. At heat flux (8000 W/m2) (12,000 W/m2), by 31.2% 64.9%, With an increase flux, runback increases. as result more airfoil. temperature ice-free area significantly higher ice-melting area, thermal resistance area. study will provide guidance for distribution coating layout make anti-/de-icing technology efficient energy-saving.
