To research performance verify of the high speed centrifugal compressor between the two different conditions with the different circumferential grooves and with untreated smooth wall, the 3-dimentional numerical simulations were performed in a high speed centrifugal compressor with the 8 different circumferential grooves casing treatment. Detailed analyses of the flow visualization at the tip of blades have exposed the different tip flow topologies between these casings. It is concluded that the major reason of the mechanism of stall margin Improvement is restrained the tip leakage vortex.
