A radial compressor has at least one compressor stage. The compressor stage includes: an impeller having moving blades on a rotor side arranged in a flow channel of the compressor stage. The flow channel is bounded by a hub contour and a housing contour or cover disc contour. Each moving blade has a flow inlet edge and a flow outlet edge. In the region of the compressor stage on the hub contour of the flow channel, initially a curvature change from a first concave curvature into a convex curvature and following this a curvature change from the convex curvature into a second concave curvature is formed; and/or on the housing contour or cover disc contour of the flow channel, initially a curvature change from a first convex curvature into a concave curvature and following this a curvature change from the concave curvature into a second convex curvature is formed.

Radial compressor

A radial compressor for a compressor arrangement comprising the radial compressor and an axial compressor includes an inlet flow channel bounded by a radially inner hub contour and a radially outer housing contour, in which inlet guide blades are arranged. Via the inlet flow channel a medium to be compressed is supplied to an impeller having moving blades. The inlet flow channel runs diagonally to an axis of rotation of the impeller.
