Soot volume fractions have been measured in turbulent diffusion flames issuing into still air for a range of gaseous and liquid fuels. The liquid fuels were prevaporized and all fuels had a common inlet temperature. It was found that flame widths were independent of fuel stoichiometry and were only a function of fluid mechanics. Soot quantities peaked at a height of 0.25 - 0.55 of flame length. Normalized radial profiles of soot volume fraction were approximately self-similar for all fuels. A characteristic soot volume fraction was defined for each fuel and found to be largely independent of residence time in the flame. The turbulent flame characteristic soot volume fraction was related to its laminar flame counterpart and was found to be predictable from the laminar flame smoke-point flow rate.
