| Outline of Final Research Achievements |
Ice crystal icing occurs in a multi-stage compressor of a jet engine, in which static temperature is about 30 degree C. The mechanism of ice crystal icing has not been well understood, and existing icing models cannot predict the icing. Therefore, a new physical model and numerical procedure for ice crystal icing have strongly been needed.
In the present study, first, I proposed a new multi-physics model for ice crystal icing, and using the model, I investigated the characteristics of ice crystal icing. Finally, applying the developed code to a multi-stage compressor of a jet engine, I obtained aerodynamic insights of ice crystal icing in the compressor, and provided some information on anti-ice crystal icing.
