Abstract:

The ingestion of ice crystals and icing inside the aero engine is a significant cause of aero engine damage and power loss. Researching on the calculation method for ice crystal/mixed phase icing, and systematically analyzing the physical model of ice crystal icing are among the major approaches to the study on the internal icing process of aero engines to ensure the safety of flight airworthiness. Focusing on the calculation of ice crystal/mixed phase icing, we establish, under the Lagrange framework, a complete numerical calculation method for ice crystal/mixed phase icing, covering multiple physical phenomena such as ice crystal motion-heat and mass transfer, ice crystal adhesion, mixed phase icing phase transition, and ice crystal erosion. The corresponding calculation program is then developed based on the NNWICE icing platform. We take the NACA0012 airfoil and two-dimensional coronal cylinder as the research objects, and simulate the icing shape under different flow conditions and cloud conditions. The effectiveness of the established calculation method is verified by comparison with the experimental results, and the influence of flow temperature and liquid water content/total water content on icing under mixed phase conditions and ice crystal water cover conditions analyzed. Comparison of the calculation results with and without the erosion effect verifies the significant influence of the ice crystal erosion effect on icing. This work lays a working foundation for further development of numerical simulation calculation of aero engine icing.
