Soot formation and oxidation in oscillating methane–air diffusion flames at elevated pressure

Not Accessible

Your library or personal account may give you access

Abstract

Comparisons with respect to the sooting tendency are made between stationary diffusion flames and diffusion flames with pulsations induced by oscillating fuel flow. Time-resolved measurements of the soot particle properties in the flames are obtained by combining Rayleigh-scattering, laser-induced incandescence, and extinction measurements into the RAYLIX method. Furthermore, flame luminosity at 590 nm and OH*-chemoluminescence signals at 310 nm are monitored to obtain data regarding the flame structure. Mean soot volume fractions of oscillating flames are significantly different from those of stationary flames with the same mean fuel flow rate; oscillations of the total amount of soot are phase shifted and asymmetric compared with fuel flow oscillations.
