Abstract
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.
Claims15
A centrifugal compressor comprising:
- an inlet;
- and
- an impeller comprising a hub and blades;
- the inlet for conveying flow to the impeller comprising guide means 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;
- wherein the flow is incident on the guide means and the guide means is arranged to guide the flow by providing at least one surface that is substantially oblique to the flow incident on the guide means, wherein each of the at least one surfaces is embodied by a passageway, wherein each passageway is a hole.
An inlet for conveying flow to an impeller of a centrifugal compressor, the inlet comprising guide means arranged to guide the flow through the inlet to induce swirl in the flow adjacent tips of blades of the impeller, the direction of swirl being the direction of rotation of the blades, without substantially disturbing the flow adjacent the hub of the impeller;
- wherein the flow is incident on the guide means and the guide means is arranged to guide the flow by providing at least one surface that is substantially oblique to the flow incident on the guide means, wherein each of the at least one surfaces is embodied by a passageway, wherein each passageway is a hole.
Guide means for fitting to an inlet of a centrifugal compressor, the guide means arranged to guide the flow through the inlet to induce swirl in the flow adjacent tips of blades of an impeller of the centrifugal compressor, the direction of swirl being the direction of rotation of the blades, without substantially disturbing the flow adjacent the hub of the impeller;
- wherein the flow is incident on the guide means and the guide means is arranged to guide the flow by providing at least one surface that is substantially oblique to the flow incident on the guide means, wherein each of the at least one surfaces is embodied by a passageway, wherein each passageway is a hole.
