ABSTRACT:
An axial flow compressor is disclosed. The axial flow compressor has a casing defining a compression passage therein. The casing has an inner surface and a center axis extending along the elongated direction of the casing. A plurality of rotor blades fixed to a disk rotate in the compression passage around the center axis. Each of the rotor blades has a tip, and the tip defines a rotation area having a width extending in the direction along the center axis. A circular concavity is formed on the inner surface of the casing extending completely around the inner surface. The circular concavity has a continuous curved shape in a sectional view, and the circular concavity is formed at a portion corresponding to a front part of the rotation area of the rotor blades.
