Apparatus for transferring energy between a rotating element and fluid
First Claim
1. A plenum for use in 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 the second group is separated from the third group by one or more inlet guide vanes of the first group; and
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;
further comprising a ring disposed at least partially within the through hole, wherein the plurality of inlet guide vanes are coupled to the ring;
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.
