Study on the Influence of Wing Icing Under Different Flight Angles and Droplet Diameters

When an airplane freezes, its appearance changes. The ice layer attached to the surface of the wing can cause changes in the shape of the wing, thereby altering the flow pattern of the airflow and reducing the lift of the aircraft. Using fluid simulation software, a finite element model of the external flow field of the NACA0012 airfoil was established, and the water droplet collection coefficient during the icing process was obtained based on the Euler method. Based on the Messinger ice growth model, the ice formation was calculated using the principles of mass and energy conservation. Further research was conducted on the influence of different flight angles, droplet diameters, and other parameters on wing icing. The results indicate that the droplet diameter is positively correlated with the maximum position of icing at the front end of the wing, as well as the thickness and area of icing. The angle of attack during flight has a significant impact on the icing range of the wings.
