Numerical simulation of ice crystal icing in an axial compressor rig

Simulation numérique du givrage par cristaux dans un banc de compresseur axial

Résumé

Numerical simulations of ice crystal icing within an experimental single-stage compressor test rig representative of realistic aeronautical engines are investigated. This paper aims to assess the icing models in CEDRE multi-physics CFD code recently developed and implemented. Gas flow, ice crystal trajectories, fragmentation dynamics and melting along the geometry are successively computed before the ice accretion in the test article is calculated using a surfacic solver that includes recently developed erosion and porosity models. Three experimental operating points are considered, with wet bulb temperatures increasing from negative to positive values and respectively exhibiting no accretion, significant accretion and moderate accretion. The comparison of simulation results with experiments for these cases shows a good agreement in terms of occurrence, location and surfacic extension of accretion phenomena. Nevertheless, a global shift in the inlet temperature is necessary to reproduce experimental results.
