Book Description
Results of bounded mixing and burning experiments in relatively long ducts are presented. The series of experiments was part of a theoretical and experimental investigation of bounded mixing with combustion within ducts of arbitrary shape. The mixing system consisted of a fuel-rich, H2-O2 rocket stream and a surrounding stream of room-temperature air. A conical mixing duct with cylindrical extensions was used. Twenty-six rocket firings were made in the test series. The system was operated in the 'downstream choking' mode (independent of back pressure) for 19 firings and in the 'back pressure dependent' mode for the remainder of the series. Stagnation pressure ratio between the two streams was varied to provide a range of data. Data presented include axial distributions of wall static pressure and radial profiles of gas composition and pitot pressure at the mixing duct exit. (Author).

Book Description
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.
