Pagination or Media Count:
A detailed assessment of supersonic combustion was carried out to identify specific research requirements in modeling turbulent reacting supersonic flows. The direct effects of pressure gradients and pressure fluctuations on turbulence were found to be potentially responsible for certain of the trends in turbulent transport and mixing rates that are observed in supersonic flows. An approach to the modeling of these phenomena is delineated, A modular model computer code for the analysis of sudden expansion dump combustors was prepared. This modular model is designed to be used parametrically in evaluating effects such as chemical kinetics limitation on flame stabilization and combustion efficiency in integral rocket ramjet and ducted rocket combustors. Keywords Pressure Interactions, Turbulence modeling, Sudden expansion combustors, Dump combustors.
