摘要

In order to study the time-space characteristics of vortex flow field in axial compressor, a time-critical CFD method was employed to numerically simulate the flow field in a single rotor. After the mass flow analysis at different axial positions in the rotor, it is found that the fluctuation value of inlet mass flow is 2% normalized by the maximum mass flow. In addition, it is also found that the oscillation of vortex flow field at suction side near the trailing edge was the main reason for the inlet mass flow fluctuation.
