Abstract:

Detailed measurements of pressure, temperature and gas composition in coflowing streams have been obtained for a variety of relative Mach numbers and density ratios. These measurements were aimed to provide a comprehensive data base from which compressibility corrections can be calculated for the turbulence models used in the JANNAF Standard Plume Flowfield Model SPF. Using a short-duration testing technique, low altitude non-reacting plume flowfields were simulated in which compressible turbulent mixing of coaxial supersonic jets occurred in a preevacuated altitude chamber. A ratio of the mixing jet diameters of 131 was obtained using an apparatus consisting of a 3-inch exit diameter nozzlesupply within the large-scale Calspan Ludwieg Tube. Originator-supplied keywords Turbulent mixing, Axisymmetric jets, Co-flowing jets, Supersonic jets, Turbulence modeling, Rocket exhaust plumes.
