Abstract

Abstract:

Post stall performance of a subsonic isolated rotor with and without a new treated casing was investigated experimentally. The aerodynamic parameters of pre stall and post stall and the recovery forms from stalled flow were compared. Using a stage by stage post stall compression system modeling technique, the numerical simulation of the rotor performance in rotating stall with and without the treated casing was accomplished. With the help of the calculation results the unusual stall phenomena were explained.

Key words: casing treatment, post stall, compressors
