  • Publication number: 20120251290
    Abstract: An aspirating face seal includes a primary seal, a secondary seal, and a biasing device. The primary seal includes a first seal component and a second seal component. The first seal component is configured to be coupled to a rotor and rotatable with the rotor.

  • Publication number: 20120227400
    Abstract: A turbine system for a multistage turbocharger and a method for utilizing the same are disclosed. The turbine system includes a high pressure turbine having an inlet for receiving a flow of fluid, and an outlet for passing the flow on extraction of work from the high pressure turbine. The system further includes a low pressure turbine, having an inlet for receiving a flow of fluid from the high pressure turbine. A diffuser connects the outlet of the high pressure turbine and the inlet of the low pressure turbine. The system also includes a bypass channel for bypassing a portion of the flow around the high pressure turbine, from upstream of the high pressure turbine to downstream of the high pressure turbine. The system includes an injector to input the bypass flow in the diffuser in a manner to reduce flow separation in the diffuser.

  • Patent number: 8135245
    Abstract: A fiber optic sensing system comprises a housing disposed in a flow path, and a fiber optic sensor. The fiber optic sensor comprises an optical fiber secured in the housing, a Bragg grating, a light source for transmitting light to the optical fiber, and a detector for detecting light filtered by the Bragg grating of the optical fiber and monitoring wavelength changes of the detected light. The fiber is substantially perpendicular to the flow path. The housing defines an opening at an upstream side to allow flow through the flow path to exert a pressure on the optical fiber and cause a deformation of the Bragg grating.

  • Patent number: 8002524
    Abstract: The present application provides a wind turbine system. The wind turbine system may include a number of blades, a number of wind speed sensors positioned on the blades, a controller in communication with the wind speed sensors, and one or more performance adjustment, mechanisms in communication with the controller. The controller activates the performance adjustment mechanisms in response to the wind speed sensors.

  • Publication number: 20110135445
    Abstract: A pressure balance seal includes a sealing surface facing an inward radial direction, and a stator interface comprising at least one surface interfacing with a stator. The pressure balance seal further includes a friction reducing feature. The friction reducing feature includes a cavity on the sealing surface. The cavity is configured to receive a fluid such that a normal force acting on the pressure balance seal is counterbalanced by a force generated by a pressure of the fluid.

  • Patent number: 7878172
    Abstract: Various embodiments of the invention relate to an intake channel of an internal combustion engine in which an adjustable position guide vane is configured to modify the velocity distribution inside the intake channel in order to vary the mean swirl number generated by the channel. The intake channel may comprise a combination of two or more ports, which can be helical or tangential, depending on their shape. By varying the velocity distribution inside the intake channel it is possible to vary the mean swirl number in an internal combustion engine. Contrary to existing systems to vary the swirl in internal combustion engines, the invention proposed does not require the separation of both ports inside the intake channel by a wall in order to achieve a variation in the swirl.

  • Publication number: 20100146968
    Abstract: A system, apparatus, and method for exhaust gas recirculation (EGR) is disclosed. The EGR apparatus includes an EGR circuit having an input configured to receive an exhaust gas from an engine exhaust port, an output configured to return the exhaust gas to an intake port of the engine, and an EGR path configured to circulate the exhaust gas between the input and the output. The EGR apparatus also includes an EGR compressor connected to the EGR circuit in the EGR path downstream of the input and EGR compressor configured to compress the exhaust gas for circulation to the output. The EGR apparatus further includes a valve system positioned in the EGR circuit and upstream of the EGR compressor to selectively cut off a flow of the exhaust gas to the EGR compressor and selectively inject ambient air into the EGR path.
