Abstract

The NACA0012 airfoil was selected as the subject of study to investigate the three-dimensional flow characteristics and aerodynamic properties of iced airfoils. Model experiments were conducted using a direct-current wind tunnel to elucidate the changes in lift and drag forces of the iced airfoil under different incoming flow velocities. Aerodynamic performance studies on wind turbine blades under various icing conditions were carried out using the STAR-CCM+ software

analyzing the impact of icing on the surface pressure coefficients and aerodynamic performance parameters of the airfoil. The research findings indicated that the presence of clear ice had the most significant impact on the aerodynamic performance of the blades. At an incoming flow velocity of 10 m/s

the lift coefficient of the airfoil decreased by 34.9% and the drag coefficient increased by 97.2% with clear ice attachment; with mixed ice

the lift coefficient decreased by 33.6% and the drag coefficient increased by 22.7%; and with rime ice

the lift coefficient decreased by 24.1% and the drag coefficient increased by 27.2%.
