FURTHER EXPERIMENTS ON MIXING AND BURNING OF BOUNDED COAXIAL STREAMS

Abstract

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.
