Temperature control within a cavity of a turbine engine

摘要

A turbine engine including an intermediate space defined between outer and inner portions of the turbine engine. A flow energizer is provided including a flow body located within the intermediate space and including an inlet port, an outlet port and a flow passage extending within the flow body between the inlet and outlet ports. The inlet port receives a flow of a first medium located within the intermediate space and the flow body injects an energizing flow of a second medium to a portion of the first medium within the flow body to create an energized flow of a mixed medium from the outlet portion, the energized flow of mixed medium creates a flow of the first medium adjacent to the flow body within the intermediate space.

1. A turbine engine including:
an intermediate space defined between outer and inner portions of the turbine engine; and a flow energizer including a flow body located within said intermediate space and including an inlet port, an outlet port and a flow passage extending within said flow body between said inlet and outlet ports, said inlet port receiving a flow of a first medium located within said intermediate space and said flow body injecting an energizing flow of a second medium to a portion of said first medium within said flow body to create an energized flow of mixed medium from said outlet portion, said energized flow of mixed medium creating a flow of said first medium adjacent to said flow body within said intermediate space, wherein the flow body includes a supply port for receiving the second medium from a source external to the outer cavity the second medium being injected into the flow passage of the flow body, between the inlet and outlet ports, to energize the flow of the first medium through the flow body.
