| Abstract: |
| The effect of transient heat transfer on the stability of axial flow compressor isanalyzed. Based on the analysis, the mathematical model is established to study the effect of transientheat transfer on compressor surge margin. According to the established model, a turbofan engine withcompression ratio 26 is investigated. The results show the validation of the model |
