    摘要： An apparatus, system and method for pumping gaseous fluid are described. The centrifugal pump of the invention homogenizes at least a portion of the gas and liquid contained in produced well fluid thereby improving the efficiency of the pump in electric submersible pump (ESP) applications and decreasing the downtime of the ESP system. The impeller of the invention comprises an increased inlet area. The centrifugal pump of the invention comprises a single shroud located on the bottom side of an impeller, an increased inlet area of the impeller and an increased clearance gap between the impeller and a diffuser. One or more truncated vanes extend substantially upstream from the single shroud, wherein each truncated vane sits at a mid-pitch location between untruncated vanes starting from the bottom side of the impeller.

    摘要： In one embodiment, a turbomachine for imparting energy to a multiphase fluid is provided. The turbomachine comprises a casing having an inlet and an outlet; an axial stage part comprising at least one axial stage; a mixed-flow stage part comprising at least one mixed-flow stage fluidly connected to the axial stage part; and a centrifugal stage part comprising at least one centrifugal stage fluidly connected to the mixed-flow stage part. The axial stage is defined by an angle between an axial impeller outlet flow and an axis parallel to a rotational axis of the shaft having a value between 0° and 5°, the mixed-flow stage by an angle having a value between 5° and 80°, and the centrifugal stage by an angle having a value between 80° and 90°.

    摘要： A turbine engine component includes a first surface to be cooled by a flow of cooling air. The first surface includes a pedestal array and a first row of contour bumps. The pedestal array includes first and second rows of pedestals extending from the first surface. The second row of pedestals runs in a direction generally parallel to the first row of pedestals. The first row of contour bumps extends from the first surface between the first row of pedestals and the second row of pedestals and runs parallel to the first row of pedestals. The first row of contour bumps is aligned such that at least one of the contour bumps of the first row of contour bumps is positioned at least one of immediately downstream of a pedestal of the first row of pedestals and immediately upstream of a pedestal of the second row of pedestals.

    摘要： A vacuum pump (100) comprises a pumping mechanism having an annular pumping chamber (112, 114, 116) extending about a longitudinal axis (107) and through which fluid is pumped by the pumping mechanism. A plenum (126) located remote from the pumping mechanism has an inlet (128) for receiving fluid to be pumped by the pumping mechanism and a plurality of outlets (132) arranged about the longitudinal axis (107) for supplying fluid to the annular chamber.
