Recent events of high-altitude turbofan engine malfunctions characterized by sudden power loss and flameouts have been attributed to ice crystal formation in the compressor core. The understanding of ice accretion on rotor/stator blades is paramount and needs to be accounted for and integrated into the gas turbine design process.Designing optimal anti/de-icing systems requires detailed understanding of complex icing phenomena and their interaction with air flow and ingested particles. Regulatory certification processes are often underpinned with expensive ice tunnel and flight tests with limited data points. High-fidelity CFD/icing models can help engineers develop a better understanding of complex icing processes and design better systems at a fractional cost.
