Turbomachine with mixed-flow stage and method |
摘要 |
Method and turbomachine for imparting energy to a multiphase fluid. The turbomachine includes a casing having an inlet and an outlet; an axial stage part including at least one axial stage; a mixed-flow stage part including at least one mixed-flow stage fluidly connected to the axial stage part; and a centrifugal stage part including 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°. |
