We have measured the first two moments of the soot particle size distribution in premixed methane/oxygen flames using the dynamic light scattering technique, photon correlation spectroscopy. Measurements were performed in a flat flame burner as a function of fuel-oxidizer equivalence ratio and height above burner. We demonstrated the ability of photon correlation spectroscopy to extract two moments, the most probable radius r0, and the geometric width sigma of an assumed zeroth-order lognormal distribution. We found that the geometric width sigma decreased with increasing height above the burner. Values for number density and total soot volume were also obtained. We discuss benefits of and problems with the measurement technique.
