Abstract
A numerical simulation method based on Eulerian Two-Phase theory was applied on airfoil under a variety of icing weather conditions. The flow field is calculated by solving the 2D N-S equations with cell-centered finite volume method. The Rime ice, Glaze ice and mixed ice were predicted on NACA0012 airfoil at 4 degree angle of attack. The simulated results agree very well with the refered experiment data, which indicates that the method is effective and correct.At last the aerodynamic characteristics of the iced airfoil was analyzed, compare different ice shape on the lift and drag coefficient, the results show that the Glaze ice has the most impact on aerodynamic characteristics.
