Ice shape predictions for a NACA0012 airfoil and collection efficiency predictions for the Twin Otter airfoil are obtained and presented. The results are validated with reference numerical and experimental data. Ice accretion modeling mainly consists of four steps: flow field solution; droplet trajectory calculations; thermodynamic analyses; and ice accretion simulation with the Extended Messinger Model. The models are implemented in a FORTRAN code to perform icing analyses for twodimensional (2D) geometries. The results are in good agreement with experimental and numerical reference data. It is deduced that increasing computational layers in calculations improves the ice shape predictions. The results indicate that collection efficiencies and impingement zone increase with increasing droplet diameter.
