A turbine is provided with a turbine rotor blade, and a turbine housing having a scroll part extending along a circumferential direction of the turbine rotor blade. The scroll part is configured such that an A/R ratio of a flow passage area A to a distance R between an axis of the turbine rotor blade and a flow passage center of the scroll part has a concave distribution at least in a part of a graph where an abscissa represents a circumferential position around the axis of the turbine rotor blade and an ordinate represents the A/R ratio.

Turbine

A centrifugal compressor is disclosed. The centrifugal compressor comprises an inlet and an impeller comprising a hub and blades. The inlet is for conveying flow to the impeller comprising guide means and is arranged to guide the flow through the inlet to induce swirl in the flow adjacent tips of the blades, the direction of swirl being the direction of rotation of the blades, without substantially disturbing flow adjacent the hub.
