Abstract:

To solve the numerical simulation problem of fan blade off in aero engine, the effects of parallel mode and grid domain decomposition strategy on computing efficiency and consistence were analyzed herein. An optimal strategy for domain decomposition and parallel mode configuration was proposed to satisfy the computation consistency requirements. The superiority of the strategy was verified by a practical engineering case.

Key words: aero engine, fan blade off, parallel computing, consistency
