FLOW INDUCER FOR A GAS TURBINE SYSTEM

摘要

A system includes an inducer assembly configured to receive a fluid flow from compressor fluid source and to turn the fluid flow in a substantially circumferential direction into the exit cavity. The inducer assembly includes multiple flow passages. Each flow passage includes an inlet configured to receive the fluid flow and an outlet configured to discharge the fluid flow into the exit cavity, and each flow passage is defined by a first wall portion and a second wall portion extending between the inlet and the outlet. The first wall portion includes a first surface adjacent the outlet that extends into the exit cavity.

1. A system, comprising:
an inducer assembly configured to receive a fluid flow from a fluid source and to turn the fluid flow in a substantially circumferential direction into an exit cavity to generate swirl of a fluid within the exit cavity, and the inducer assembly comprises:
a plurality of flow passages, each flow passage comprises an inlet configured to receive the fluid flow and an outlet configured to discharge the fluid flow into the exit cavity, and each flow passage is defined by a first wall portion and a second wall portion extending between the inlet and the outlet, and the first wall portion comprises a first surface adjacent the outlet that extends into the exit cavity; wherein the inducer assembly is configured to be stationary relative to a rotational axis of a gas turbine engine during operation of the gas turbine engine.
