Abstract:The numerical simulation that was verified by an experiment was
   conducted to study the high-loaded compressor cascade incidence. The
   influence of the boundary layer suction on incidence is explored and its
   control mechanism is explained from the perspective of vortex system.
   Results show that the performance of high-loaded cascade is almost in
   same in a little range of incidence And the secondary flow increase with
   the growth of positive incidence and expand along span rapidly. The
   mixing loss in cascade reduced significantly via the boundary layer
   aspiration .In the meantime, the aspiration on suction side is superior
   to end-wall in terms of incidence performance.
