Abstract: A pressure exchanger includes a rotor configured to exchange pressure between a first fluid at a first pressure and a second fluid at a second pressure. The rotor forms ducts that are routed from a first distal end to a second distal end. The pressure exchanger further includes a first end cover that forms a high pressure in (HPIN) port configured to provide the first fluid at the first pressure in a substantially axial direction into the ducts. The first end cover forms a low pressure out (LPOUT) port configured to receive the first fluid from the ducts at a third pressure. The pressure exchanger further includes a second end cover that forms a low pressure in (LPIN) port configured to provide the second fluid at the second pressure into the ducts and forms a high pressure out (HPOUT) port configured to receive the second fluid from the ducts at a fourth pressure.

Abstract: A system includes a monitoring system to monitor an operational parameter of a bearing assembly within a hydraulic turbocharger. The bearing monitoring system includes at least one sensor to monitor a relative position or operational parameter of one or more rotating components of the bearing assembly.

Abstract: A system includes a hydraulic transfer system configured to exchange pressures between a first fluid and a second fluid, where the first fluid has a pressure higher than the second fluid, includes a sleeve comprising an elliptical shape, a cylindrical rotor disposed within the sleeve in a concentric arrangement, where the cylindrical rotor is configured to rotate circumferentially about a rotational axis and has a first end face and a second end face disposed opposite each other. The system includes a first and second end cover having a first and second surface which interface with a first and second end face of the rotor. The system includes a first and a second radial clearance disposed between the sleeve and the cylindrical rotor, where the radial clearances are configured to increase or decrease based at least in part on a pressure differential.

Abstract: A system includes a rotary isobaric pressure exchanger (IPX) having an oblique ramp disposed within a fluid inlet of an end cover at an oblique angle configured to direct a fluid toward an interior surface of a channel within a rotor to facilitate rotation of the rotor. In addition, the system may include one or vanes disposed within the fluid inlet to further direct the fluid toward the interior surface. Further, the system may include one or more passages extending from the fluid inlet toward a surface of the end cover that interfaces with the rotor, where the one or more passages utilize the fluid to apply additional force to the rotor to facilitate rotation.
