Non-Reacting Turbulent Mixing Experments. Revision 1
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 13:1 was obtained using an apparatus consisting of a 3-inch exit diameter nozzle/supply within the large-scale Calspan Ludwieg Tube. Originator-supplied keywords: Turbulent mixing, Axisymmetric jets, Co-flowing jets, Supersonic jets, Turbulence modeling, Rocket exhaust plumes.
