Airfoil is one of the most important parts of wind turbine and aircraft, it has a wide range of important applications. The effect of icing on aerodynamic performance of airfoil cannot be ignored. Considering the icing NACA 0012 airfoil unsteady pitch oscillation process, a thorough 2D unsteady computational fluid dynamic analysis was performed based on moving-mesh method and the k −ω shear stress transport turbulence model. The aerodynamic performance of NACA 0012 airfoil before and after icing is calculated. The unsteady pitch oscillation of airfoil under three ice conditions is simulated, the stall characteristics and aerodynamic/ torque coefficients of the icing airfoil with the angle of attack were studied. the hysteria effect of aerodynamic coefficients during the oscillation of the icing airfoil was analyzed. the influence law of key parameters on the flow field structure and aerodynamic performance of the icing airfoil was obtained, which provides a reference for the study of the influence of icing on the aerodynamic performance of the oscillating airfoil.
