Abstract : An experimental and theoretical investigation of bounded turbulent mixing with chemical reactions is described. Configurations which are applicable to the air-augmented rocket are considered. Experimental results are presented for a mixing apparatus in which a fuel-rich O2-H2 rocket stream was mixed with a secondary airstream inside a conical duct. An integral mixing theory is described, in which conservation equations are satisfied across the duct. The inviscid portions of the duct flow are considered onedimensional, and the mixing zone profiles are assumed to exhibit shape similarity. The theory is extended to include the downstream regime where the mixing region extends across the entire duct. Correlations of the theory with incompressible and reactive compressible mixing experiments indicate that the theory provides a satisfactory over-all representation of the bounded mixing process.
