Abstract
In an axial flow compressor including a rotor wheel having a plurality of rotating blades mounted thereon, said rotor being arranged to rotate about a central axis of the compressor, there is provided an aerodynamically profiled ring arranged concentrically to the compressor axis in front or upstream of the plurality of rotating blades in order to define between an outer surface of the profiled ring and an inner wall of the compressor casing an annular flow channel which converges in the direction of flow through the compressor. A plurality of stationary blades are located upstream of the profiled ring.
