Abstract

Full-annulus unsteady simulations were carried out to obtain the internal flow field structure in an axial flow compressor at design point and near stall point, especially the internal flow of compressor at stall point was studied. Results show that, at near stall point, shock waves in rotor passages move forward, and form stronger shock waves by combining with the detached shock waves. The shock waves at 20% span of rotor move forward most seriously, leading to a heavy boundary separation on the rotor suction side. Influenced by rotor wake flow, large scale separation zones generated at stator corner and space ring vortex formed.

Key words： compressor; flow-field; unsteady; shock wave; separation
