A DIFFUSER APPARATUS IN A TURBOMACHINE

摘要

A diffuser apparatus (20) in a turbomachine is provided comprising a diffuser structure (30) and stabilizing structure (40,50). The diffuser structure includes inner (32) and outer walls (34) defining a flow passageway (36) through which gases flow and diffuse such that kinetic energy is reduced and pressure is increased in the gases as they move through the passageway. The stabilizing structure stabilizes a separated gas recirculation zone (z1, z2)
