OPTIMIZED CIRCUMFERENTIAL GROOVE CASING TREATMENT FOR AXIAL COMPRESSORS

摘要

A compressor (24) is provided. The compressor (24) includes a rotating member configured to rotate about an axis (A-A') and a static member (102) radially adjacent the rotating member with a clearance between the static member (102) and the rotating member. A first groove (104) is disposed circumferentially about the static member (102) and radially adjacent the rotating member. A second groove (106) is disposed circumferentially about the static member (102) and a first axial distance (L3) aft of the first groove (104). A third groove (108) is disposed circumferentially about the static member (102) and a second distance (L5) aft of the second groove (106), wherein the first distance (L3) is different from the second distance (L5).
