IDDESS Numerical Study of Coupled Flow Between Compressor Transition Section and Upstream Stator
The compressor transition section with upstream stator taken as the research object,the unsteady IDDES calculation method is used to analyze the flow characteristics of the vortex structure in the compressor transition section channel under the influence of upstream stator,and the loss mechanism of the transition section channel is studied.The results show that the wake vortex will migrate to the hub wall near the periodic surface when moving downstream.The corner separation vortex is continuously mixed with the upstream wake vortex and the horseshoe vortex at the leading edge of the strut from the maximum thickness of the strut to the exit of the transition section,tending to develop towards the mainstream.The vortex structure at the outlet of the transition section is mainly distributed in the center of the channel near the hub wall.
