Abstract

© 2015 by Patton M. Allison. In the current work, the piloted premixed jet burner (PPJB) configuration developed at the University of Sydney is used to characterize four highly turbulent flame cases with increasing turbulence intensities, increasing Karlovitz numbers, and decreasing Damköhler numbers. High-resolution, planar Raleigh scattering is applied to measure the two-dimensional temperature field at several axial locations within the premixed jet flame cases. Analysis of the structure of the temperature field shows that with increasing jet velocities, the flame brush and thermal zone is broadened. In contrast, the thickness of individual thermal layers decreases with increasing jet velocity as the degree of turbulence-chemistry interactions are enhanced with increasing Karlovitz number.
