Abstract

Abstract

Numerical simulations were carried out to investigate interaction between a single stage compressor and pylons.Analysis of results shows that the pylons cause large disturbance on flowfield in compressor,and that the disturbance imposes significant effects on the flow field of rotor,which brings the blades of rotor under large unsteady surface pressure.Flow near the pylon leading edges was drawn out,which almost completely shielded the influence of pylons on rotor.
