TURBOMACHINE EXHAUST FRAME

摘要

A turbomachine exhaust frame includes a body having an outer barrel member (50) including an outer surface and an inner surface and an inner barrel member (52) having an outer surface and an inner surface. A first flow passage (61) is defined by the outer surface and the inner surface of the outer barrel member. A second flow passage (68) is defined by the outer surface and the inner surface of the inner barrel member. A first cooling circuit (91) having a first inlet and a first outlet is connected to the first flow passage, and a second cooling circuit (94) having a second inlet and a second outlet is fluidically connected to the second flow passage. A nozzle (130) is arranged in the first flow passage and is connected to the first cooling circuit. The nozzle introduces a fluid flow into the first flow passage in at least one of an axial and an annular direction.
