The aim of this study is to show the application of an Eulerian method for ice crystal icing to a three-element airfoil in high-lift configuration. The ice crystals have been modeled as non-spherical particles which are subject to convection and/or phase change along their trajectories. On impact with the airfoil surface the ice crystals will either stick to the surface or rebound from the airfoil unchanged or as a number of fragments. The evolution of the secondary cloud containing these rebounded or shattered fragments is computed as well. It is concluded that an Eulerian method is a convenient method to compute trajectories of (melting) ice crystals for a high-lift configuration such as a three-element airfoil if certain limitations with regard to the secondary cloud of particles are taken into account.
