Abstract

To address the paucity of experimental data on well-documented turbulent jet flames at elevated pressures, a high pressure rig has been used to explore turbulent nonpremixed syngas flames at elevated pressures and very high Reynolds numbers. Composite images of the flames reveal small changes in flame length that are in agreement with previous empirical correlations. OH-PLIF images are used to visualize the flame structure, revealing an OH layer that gets progressively thinner as pressure increases. A corrugation factor is defined and used to show that flame front corrugation is influenced by increases in Reynolds number and axial distance from the nozzle, but not pressure.
