Simulation of Ice Shedding From Rotating Parts Using Phase-Field Fracture and Cohesive Zone Models

The aim of this work is to develop a numerical methodology for the simulation of ice shedding from rotating parts in an aircraft engine. The goal is to estimate the size of the detached ice blocks and to assess the feasibility of such simulations for 3D industrial cases. This work relies on mechanical properties available from recent collaborative projects on the characterization of adhesive and cohesive properties of accreted ice of different substrates. The simulations are performed with the finite element software Z-set using a phase-field fracture model coupled to a cohesive zone model to capture cracks in the ice volume, at the ice/substrate interface or in mixed modes.
