Abstract

In this paper a numerical investigation of 5 circumferential grooves in different configurations applied to a subsonic compressor stage is presented. After a brief review of circumferential groove studies from the past, a detailed analysis of the flow mechanisms in the grooves and at the interface between the grooves and the main flow is given. Different ruling flow mechanisms were identified in the grooves depending on their relative axial position to the rotor chord.
