Abstract
A centrifuge turbo machinery includes an impeller which rotates about an axis to pressure-feed fluid flowing along the axis to an outer side in a radial direction, and a casing which accommodates the impeller and has a facing surface facing the impeller in an axial direction. A convex portion relatively close to the impeller and extending in the radial direction and a concave portion relatively spaced apart from the impeller and extending in the radial direction are alternately and continuously formed on the facing surface in a circumferential direction.
