A stator blade for a centrifugal compressor having a front portion configured to generate one or more strear-wise vortices in the gas flow around the stator blade in order to avoid and/or delay a detachment of the gas flow from the suction surface of the stator blade especially when the centrifugal compressor is not operating at its operational design speed.

A scroll for use in conjunction with a fluid compressor is described. The scroll comprises a fluid inlet adapted to receive a fluid flow and a fluid outlet adapted to discharge the fluid flow. The scroll further comprises a scroll-shaped wall defining an inner flow volume. At least one blade is provided in the inner flow volume of the scroll. The blade is configured and arranged for correcting a direction of the flow of fluid in the flow volume when the scroll is operating in off-design conditions.
