In this study an Eulerian method is utilized to compute ice crystal trajectories and impact in the flow through a stator-rotor-stator cascade. On their trajectories the (non-spherical) ice particles are subject to evaporation/sublimation and melting and they will deposit either fully or partially on the surface of the subsequent blades of the parts of the cascade. Results of the total water content, melting ratio and catching efficiency will be compared for particles of different size and sphericity.
