Abstract

In some embodiments, a plenum of an apparatus for transferring energy between a rotating element and a fluid may include a through hole disposed through the plenum; a plurality of inlet guide vanes disposed proximate a peripheral edge of the through hole, the plurality of inlet guide vanes comprising a first group of inlet guide vanes having a symmetrical profile, a second group of inlet guide vanes, and a third group of inlet guide vanes, wherein each inlet guide vane of the second group and third group have a cambered profile, and wherein each inlet guide vane of the third group has a different cambered profile from each other inlet guide vane of the third group.

Claims

1. A plenum of an apparatus for transferring energy between a rotating element and a fluid, the plenum comprising:

a through hole disposed through the plenum;

a plurality of inlet guide vanes disposed proximate a peripheral edge of the through hole, the plurality of inlet guide vanes comprising a first group of inlet guide vanes having a symmetrical profile, a second group of inlet guide vanes and a third group of inlet guide vanes, wherein each inlet guide vane of the second group and third group have a cambered profile, and wherein each inlet guide vane of the third group has a different cambered profile from each other inlet guide vane of the third group.

2. The plenum of claim 1, wherein the plurality of inlet guide vanes are disposed symmetrically about the peripheral edge of the through hole.

3. The plenum of claim 1, wherein the first group of inlet guide vanes are disposed proximate a top and a bottom of the through hole.

4. The plenum of claim 3, wherein the first group of inlet guide vanes are disposed such that inlet guide vanes disposed proximate the top of the through hole are symmetric to inlet guide vanes disposed proximate the bottom of the through hole with respect to a vertical axis of the plenum.

5. The plenum of claim 1, wherein the second group of inlet guide vanes are disposed proximate a first side of the through hole and the third group of inlet guide vanes are disposed proximate a second side of the through hole opposite the first side.

6. The plenum of claim 1, wherein at least one of the plurality of inlet guide vanes comprises a length that is different from another of the plurality of inlet guide vanes.

7. The plenum of claim 1, wherein the apparatus is a centrifugal compressor.

8. The plenum of claim 1, further comprising a ring disposed at least partially within the through hole, wherein the plurality of inlet guide vanes are coupled to the ring.

9. The plenum of claim 8, wherein each of the plurality of inlet guide vanes are rotatably coupled to the ring, and wherein each of the plurality of inlet guide vanes rotate about an axis of rotation of each of the plurality of inlet guide vanes.

10. The plenum of claim 9, wherein each of the plurality of inlet guide vanes rotate an angle of about −

30 to about 70 degrees with respect to a central axis of the plenum.

11. An apparatus for transferring energy between a rotating element and a fluid, comprising:

an housing having an inlet to allow a flow of fluid into the housing;

a plenum defining a flow path fluidly coupled to the inlet, the plenum having a through hole disposed through the plenum;

a plurality of inlet guide vanes disposed proximate a peripheral edge of the through hole, the plurality of inlet guide vanes comprising a first group of inlet guide vanes having a symmetrical profile, a second group of inlet guide vanes and a third group of inlet guide vanes, wherein each inlet guide vane of the second group and third group have a cambered profile, and wherein each inlet guide vane of the third group has a different cambered profile from each other inlet guide vane of the third group.

12. The apparatus of claim 11, wherein the plurality of inlet guide vanes are disposed symmetrically about the peripheral edge of the through hole.

13. The apparatus of claim 11, wherein the first group of inlet guide vanes are disposed proximate a top and a bottom of the through hole.

14. The apparatus of claim 13, wherein the first group of inlet guide vanes are disposed such that inlet guide vanes disposed proximate the top of the through hole are symmetric to inlet guide vanes disposed proximate the bottom of the through hole with respect to a vertical axis of the plenum.

15. The apparatus of claim 11, wherein the second group of inlet guide vanes are disposed proximate a first side of the through hole and the third group of inlet guide vanes are disposed proximate a second side of the through hole opposite the first side.

16. The apparatus of claim 11, wherein at least one of the plurality of inlet guide vanes comprises a length that is different from another of the plurality of inlet guide vanes.

17. The apparatus of claim 11, wherein the apparatus is a centrifugal compressor.

18. The apparatus of claim 11, further comprising a ring disposed at least partially within the through hole, wherein the plurality of inlet guide vanes are coupled to the ring.

19. The apparatus of claim 18, wherein each of the plurality of inlet guide vanes are rotatably coupled to the ring, and wherein each of the plurality of inlet guide vanes rotate about an axis of rotation of each of the plurality of inlet guide vanes.

20. The apparatus of claim 19, wherein each of the plurality of inlet guide vanes rotate an angle of about −

30 to about 70 degrees with respect to a central axis of the plenum.
