Abstract

This article focuses on the numerical simulation of ice accretion and ice shedding on the surface of an aero-engine rotating cone, analyzing the effects of different rotational speeds. Using a three-dimensional steady-state model and the bilinear cohesive zone model, the study finds that increasing rotational speed decreases surface pressure and enhances temperature gradients, while significantly increasing the water droplet collection coefficient and ice accretion thickness on the cone surface. Ice shedding is more likely to occur downstream of the ice accretion, where maximum equivalent and shear stresses are observed. The findings provide insights into ice formation and detachment mechanisms relevant to aero-engine safety and performance.
