✦ Synopsis

Carbon monoxide emission indices were measured for turbulent jet flames produced by burning either methane, propane, ethylene, or a carbon monoxide-hydrogen mixture in air. Flame conditions were varied by changing the initial jet velocity or diluting the fuel with N 2. The CO emissions correlate strongly with flame luminosity, and ostensibly, with in-flame soot, consistent with CO/soot measurements in laminar flames, low-Reynolds number turbulent jet flames, pool fires, and other fire-related flame environments. The present measurements indicate that the physical and chemical processes controlling CO emissions from diffusion flames are similar over a wide range of flow conditions.

In this paper we explore the effects of differential diffusion in nonpremixed turbulent jet flames. Pulsed Raman scattering spectroscopy is used to measure temperature and species concentrations in chemically reacting jets of H2/CO 2 into air, over a range of jet Reynolds numbers from 1,000 to 30,00
