    Abstract: A purpose of the invention is to reduce size and weight and to make assembly easier while maintaining high response performance or the like required for a turbocharger for an automobile. A rotor blade upstream flow channel space s2 of a cylindrical portion 22 is gradually reduced from an upstream side toward a downstream side in a swirling direction of exhaust gas e in accordance with a reduction in volume of a scroll chamber s1. That is, a back plate 24 is formed so as to swell out to a rotor blade side gradually from the upstream side toward the downstream side in the swirling direction of the exhaust gas e in accordance with the reduction in volume of the scroll chamber s1. The swelling portion of the back plate 24 approaches a rotor blade 16 beyond a communication portion d, and reaches a position adjacent to a leading edge 16a of the rotor blade 16 at a termination end thereof. Therefore, the flow channel space s2 disappears substantially at this termination end.

  • Publication number: 20130251514
    Abstract: A regenerative blower includes an annular housing assembly that surrounds a rotating impeller and defines a toroidal flow channel, an inlet to admit fluid to the toroidal flow channel, an outlet to discharge fluid from the toroidal flow channel, a low fluid-pressure region of the toroidal flow channel proximate to the inlet, and a high fluid-pressure region of the toroidal flow channel proximate to the outlet. A non-contact interaction between concentric surface contours of the impeller and the housing assembly form opposed concentric fluid pathways between the impeller and the housing assembly from the high to low fluid-pressure regions of the toroidal flow channel. The opposed concentric fluid pathways are so convoluted as to restrict fluid from flowing therethrough from the high fluid-pressure region of the toroidal flow channel to the low fluid-pressure region of the toroidal flow channel.

  • Patent number: 8523517
    Abstract: The aerodynamically shaped, symmetrical cross-sectional profile for the struts or the fairing (7) of struts and service lines in the bypass duct and the core-flow duct of a turbofan engine is defined by a course of the local thickness (T) and a position of maximum thickness (PMT) on both sides over the central chord (C) extending from the leading edge (LE) to the trailing edge (TE) of the strut or fairing (7). In order to avoid flow separations the course of the local thickness (T) between the position of maximum thickness (PMT) and a trailing-edge position (PTE), which is at 95 percent of the chord length, has a first turning point (WP1) with a trailing-edge thickness (TET) and a subsequent second turning point (WP2).

  • Patent number: 8328499
    Abstract: A method and apparatus is provided for harnessing the wind energy generated by vehicles passing on a roadway. A roadway is provided with a trench extending from a surface of the roadway. The trench may be provided along an extended stretch of the roadway or as a discrete trench section spaced apart along the roadway. The trench or trench section may be provided near the middle of a lane making up the roadway such that a vehicle travelling on the roadway passes over the trench. In this manner the wind displaced by the passing vehicle is directed into the trench and experienced by a wind turbine or wind generator provided within the trench. The trench is covered by a structure configured to direct the displaced wind inside the trench. The wind turbine converts the kinetic energy of the wind into mechanical energy that is then converted into useable power.
