Abstract: A shroud for a compressor is provided. The shroud may include an inner annular member and an outer annular member. The inner annular member may include an abradable material disposed between a first end portion and a second end portion thereof. The inner annular member may further be contoured between the first end portion and the second end portion thereof. The inner annular member may be configured to be disposed proximal an impeller of the compressor such that the inner annular member and the impeller define a clearance therebetween. The outer annular member may extend axially from the second end portion of the inner annular member. The outer annular member may be configured to compliantly mount the shroud with a casing of the compressor.
