    Abstract
  • Through numerical simulation based on the experimental results,the topology theory and the rules of surface pattern were used to analyze the development of the secondary vortex with several different incidences in the compressor cascade.Then the topology patterns of the separation structures were presented.The result shows that the range of the suction surface separation expands and the unsteady effect of the flow field increases with the increase of the incidence.At the same time,the separation model transits from the open separation to the closed separation.And the corner vortex is not sensitive to the variation of the incidence.At last,the author proposed a new vortex model for the compressor cascades.
