摘要：
The paper starts with a brief introduction of the significant influence of unsteady flows on turbomachinery performance, then summarizes the time and space periodicities of turbomachinery unsteady flows arising from blade row interaction and blade vibration. The time and space periodicities can be made use of to develop efficient reduced order numerical methods for analysing these unsteady flows. This paper classifies these reduced order methods based upon their own features and provides detailed discussions about their pros and cons and their applications in turbomachinery aeroelasticity. Finally, the key technologies and the future development prospects of reduced order methods are outlined. © 2021, Editorial Department of Journal of Propulsion Technology. All right reserved.
