摘要：
Numerical modeling of the icing process on the wing profile NACA 0012 is conducted. The influence of pressure and temperature of the incoming gas-dynamic flow, the attack angle of the profile, the water content of the medium, the wing surface roughness, the profile exposure in the flow on the aerodynamic profile characteristics is studied. The mathematical model is given that takes into account the direct modeling of contours of ice build-up formed as a result of impact of droplets on the wing profile, processes of ice accretion and sublimation, evaporation of a liquid film, transport of liquid along the profile surface. The studies were carried out using the ANSYS engineering analysis system FENSAP-ICE 3D on a high-performance computing cluster. Research of icing processes is equally important for ground application of aircraft engines and compressors in gas transmittal units in the Far North.
