Simulation of Airfoil Icing and Aerodynamic Characteristics(AIAAC)Based on Fluent and Fensap-Ice
Ice on the wings of the drone severely limited its maneuverability.In this paper,based on the numerical simulation method of Fluent and Fensap ICE,the coupling simulation calculation of the icing process of the wing of a UAV was carried out.The influences of icing parameters such as icing time,flight speed,MVD and LWC on the icing process of the airfoil were studied,and the aerodynamic performance of the airfoil was analyzed based on the two-di-mensional airfoil surface after icing.It is found that with the increase of icing time,flight speed,average diameter of water droplets(MVD)and content of liquid water in clouds(LWC)and other parameters,the influence of aircraft ic-ing on its aerodynamic characteristics is more and more severe,but the variation degree of icing size,aerodynamic per-formance and the causes of the changes are different.By analyzing the changes of aerodynamic performance before and after icing,it can provide guidance for the selection of icing state and the design of anti-icing device in different envi-ronments.
