Ice accretion is the phenomenon that super-cooled water droplets impinge and accrete on a body. It is well known that ice accretion on blades and airfoils leads to performance degradation and severe accidents. For this reason, experimental investigations have been done using flight tests or an icing tunnel. However, it is too expensive, dangerous, and difficult to set actual conditions. Hence, computational fluid dynamics is useful to predict ice accretion. The rotor blade is one of the aircraft components where ice accretes. Therefore, we focus on the ice accretion on a rotor blade in this study. We simulate three-dimensional icing phenomena on the rotor blade of a commercial axial fan. The ice accretion on the rotor blade is numerically discussed.
