Abstract
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 has caused severe accidents. One major cause of accidents due to ice accretion is supercooled large droplets (SLD). In this study, we apply a SLD model to a rotor blade of a jet engine under an icing condition, and the numerical results with/without the model are compared. We confirm that with the model, the volume of ice near the hub is larger than the result without the model. Through this study, the influence of the SLD icing model in a jet engine is numerically clarified.
