A purely Eulerian numerical approach to track secondary droplets resulting from the bouncing and splashing of supercooled large droplets is proposed. Different models have been analyzed on the basis of their ability to provide initial conditions for the re-injected mass. The numerical method is evaluated for clean and iced NACA 23012 geometries in SLD conditions. Tests are performed to compare the accuracy of the proposed method with other numerical methods and icing tunnel experiments. Improvement is observed in the accuracy of the impingement limits, as well as the local collection efficiency, compared to other models. No improvement is seen in the prediction of local collection efficiency for severely contaminated geometries, and an analysis of potential influencing factors is reported.
