Compact, light weight eductor oil cooler plenum and surge flow plenum design

摘要

An eductor assembly (104) is provided that includes a primary nozzle (114), a cooler plenum (120), and a surge plenum (122). In one embodiment, and by way of example only, the primary nozzle (114) is configured to accelerate and discharge turbine exhaust gas therefrom and the cooler plenum (120) surrounds the primary nozzle (114) and includes at least a fluid inlet (134) and a fluid outlet (136). The surge plenum (122) partially surrounds the primary nozzle (114) and the cooler plenum (120) and includes at least a fluid inlet (154) and a fluid outlet (156). The surge plenum fluid outlet (156) axially aligns and is coterminous with the cooler plenum fluid outlet (136).
