Fluid mixing apparatus for mixing the coaxially flowing streams of fan air and primary exhaust within a turbofan engine are disclosed. Each of the disclosed arrangements include a generally tubular mixer section that extends axially rearward from the engine turbine flange. The mixing apparatus includes axially extending regions in which contiguous portions of the fan stream are induced to flow radially inward to penetrate the primary flowstream and includes axially extending regions in which contiguous portions of the primary flowstream are induced to flow radially outward to penetrate the fan stream. The regions inducing the outwardly directed flow of the primary flowstream and the regions inducing the inwardly directed flow of the fan stream are circumferentially interspersed with one another to establish a flow pattern which causes mixing to occur along the axial length of the mixing apparatus and causes mixing to continue within a common exhaust duct located aft of the mixing apparatus. In some of the disclosed arrangements, a series of deflection vanes are positioned across each of the regions that divert the fan flowstream and each of the regions that divert the primary flowstream. In other arrangements, only the regions for diverting fan flow or the regions for diverting primary flow include such deflection vanes. In each arrangement an annular free mixing boundary is formed along the forward portion of the mixing apparatus to minimize the effect of the mixer geometry on the engine cycle of the gas turbine engine in which the apparatus is employed.

Mixing apparatus for mixing first and second fluid streams with one another wherein said first fluid stream flows through an inner duct and said second fluid stream flows through an annular passageway formed between said inner duct and an outer duct that coaxially surrounds said inner duct, the direction of fluid flow of said first and second fluid streams substantially being in the same axial direction relative to said coaxially arranged inner and outer duct extending axially in the direction of fluid flow beyond the terminus of said inner duct to define a common duct for the mixing of said first and second fluid streams, said mixing apparatus comprising: an annular free mixer mountable to said terminus of said inner duct to extend in said axial direction of fluid flow, said annular free mixer having a cross-sectional geometry at the forwardmost end thereof substantially corresponding to the cross-sectional geometry of said terminus of said inner duct, said annular free mixer having a smoothly contoured terminating edge for permitting those regions in said first and second fluid streams flowing contiguous with the boundaries of said free mixer to partially mix with one another as said contiguous regions flow past said terminating edge of said free mixer; a plurality of relatively thin elongate plates, each of said plates being substantially rectangular in geometry and having first and second longitudinal edges, said plates being mounted to extend rearwardly from circumferentially spaced apart positions along said terminating edge of said annular free mixer to define a plurality of axially extending open regions with each of said plates forming a boundary wall that separates one of said open regions from an adjacent one of said open regions, said first and second longitudinal edges of each of said plates being respectively intersecting with the circumference of first and second concentric circles positioned in a plane transverse to said direction of fluid flow to define the transverse cross-sectional geometry of said plurality of open regions as segments of the annular region between said first and second concentric circles; means for inducing a component of outward radial flow of said first fluid stream through a first plurality of said axially extending open regions and for inducing a component of inward radial flow of said second fluid stream through a second plurality of said axially extending open regions, said radially induced flow of said first fluid stream penetrating into said second fluid stream and said radially induced flow of said second fluid stream penetrating into said first fluid stream, individual open regions of said first plurality of open regions for outward radial flow of said first fluid stream being interspersed in circumferential alternation with individual open regions of said second plurality of open regions for inward radial flow of said second fluid stream, said means for inducing said radial flow of said first and second fluid streams including a first and second plurality of deflection vanes respectively mounted within individual open regions of said first and second pluralities of axially extending open regions to extend between adjacent ones of said circumferentially spaced-apart, axially extending plates, said deflection vanes being spaced-apart from one another along said axially extending plates and canted relative to the axial flow direction of said first and second fluid streams, said deflection vanes being canted to expose the forwardmost boundary of each of said deflection vanes with that one of said first and second fluid streams being induced to include a radial flow component, each individual deflection vane of said first and second pluralities of deflection vanes being contoured relative to the direction transverse to said direction of fluid flow to position the surface of each of said deflection vanes coincident with an arc of a circle that is concentric with said first and second concentric circles.
