Calculating the flow of thin water film and the accretion of ice layer is important for predicting of aircraft icing. The Myers model takes into consideration the water flow driven by air shear and pressure, and the ice accretion rate influenced by heat conduction and convection among ice layer, water film and ambient air. When the Myers model is used to predict aircraft icing, undesired ice horn will occur as the model's criterion for determining the ice type is simple. To solve this problem, the criterion for ice type determination is revised, and an effective numerical method is presented to solve the equation for water flow and ice accretion. The single-step and multi-step computational results of the two-dimensional NACA0012 airfoil are presented and compared with the experimental results. For glaze ice accretion at lower temperature, the computational results agree well with the experimental results. For glaze ice accretion at higher temperature, the computational results of the upper ice horn are slightly different from the experimental results. The computational results of ice accretion on the three-dimensional GLC-305 airfoil are also presented and compared with the experimental results. The computational results of the ice horn thickness is slightly less than the experimental results, but the computational results of the overall ice accretion tendency agree well the experimental results.
