Abstract
Post-stall performance of a subsonic one-stage compressor with and without a new treated casing was investigated experimentally. The aerodynamic parameters of pre-stall and post-stall and recovery forms from stalled flow were compared. Using an unsteady stage-by-stage compression system modeling technique, the numerical simulation of compressor performance recovery from rotating stall with and without the treated casing was accomplished. The calculation results verify that the method of casing-treated can improve the stalling recoverability of the compressor.
