    Abstract
  • Based on the numerical simulation method,frequency spectrum analysis and structure analysis were conducted for the three dimensional unsteady flow inside the compressor rotor.Through the analyses of the time-average flow field and the animated isentropic cartoon,we recognize the characteristics of the flow field,the existence range of the vortex shedding.The interaction of the leading edge and trail edge vortex and corner vortex was investigated,and the rule of their development and their effect to each other were also discussed along with the frequency spectrum analysis.For separated flow,dynamic demonstration graph and spectrum analysis were used to estimate the vortex shedding and corner vortex frequencies.The work can be used as theoretical foundations for active and passive control of compressor to improve its performance.
