Abstract

An exhaust mixer assembly for a gas turbine engine (10) includes a core passage (26) directing a core flow. An outer annular passage (24) directing a bypass flow surrounds the core passage (26). A lobed exhaust mixer (32) communicating with the passages has upstream and downstream ends (36, 38) and a lobed annular wall (34) therebetween. The annular wall (34) defines alternating inner and outer radial lobes (42, 44) having exits defining a mixing plane for the core and bypass flows. The outer lobes (44) protrude into the outer passage (24) and the inner lobes (42) protrude into the core passage (26). The inner lobes (42) include troughs (46) and the outer lobes (44) include crests (48). Adjacent inner and outer lobes (42, 44) have radial walls (50) interconnecting adjacent troughs (46) and crests (48). Protrusions (52) extend axially from a downstream end (38) of the annular wall (34) to form a mixer jagged trailing edge (54). Each protrusion (52) is spaced apart from one another and protrudes independently from one along the annular wall (34).
