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, wherein each inlet guide vane of the second group has same cambered profile, and further wherein each inlet guide vane of the third group has a different cambered profile from each other inlet guide vane of the third group.

Apparatus for transferring energy between a rotating element and fluid

A device for controlling the flow in a turbomachine, in an embodiment, a centrifugal compressor; the device includes a plurality of fixed blades and a plurality of adjustable blades adjacent to the plurality of fixed blades so that each of the adjustable blades has an aerodynamic interaction with one of the fixed blades; each of the adjustable blades is pivoted to rotate about a fixed axis substantially located at the center of pressure of the adjustable blade; the center of pressure is evaluated when the blade is at a reference orientation.

Embodiments of an apparatus for transferring energy between a rotating element and a fluid are provided herein. 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; and 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 cambered profile and a second group of inlet guide vanes disposed radially inward of the first group of inlet guide vanes, wherein the first group of inlet guide vanes are in a fixed position with respect to the plenum and the second group of inlet guide vanes are movable with respect to the plenum.

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.

An exemplary turbocharger system for an internal combustion engine is provided. The turbocharger system includes a first turbine and a second turbine. The first turbine is in fluid communication with the internal combustion engine. The first turbine receives a first portion exhaust gas discharged from the internal combustion engine and provides a first turbine exhaust gas. The second turbine is in fluid communication with the first turbine via an inter-stage channel. The inter-stage channel transports the first turbine exhaust gas from the first turbine to the second turbine. The inter-stage channel is in thermal connection with an exhaust gas recirculation channel defined between an inlet and an outlet of the internal combustion engine. The first turbine exhaust gas flowing through the inter-stage channel is capable of being heated by a second portion exhaust gas discharged from the internal combustion engine and flowing through the exhaust gas recirculation channel.
