- Abstract
Software and methods allowing one to model the processes of formation of a 'barrier' ice on the unprotected part of an airfoil have been developed with the use of the Reynolds-averaged Navier-Stokes equations for a compressible gas, which are closed with the aid of the Spalart-Allmaras model of turbulence. An inertial model is used to describe the motion of overcooled water droplets. In modeling the process of ice accretion, differential equations of mass, momentum, and energy conservation are used for each element of the surface. The initial equations are made discrete by means of the control volume approach. The influence of the height of ice accretions and of their location on the character of air-droplet flow past a NACA 0012 airfoil and on its aerodynamic characteristics has been analyzed.
