“…where H is the fuel hydrogen content (percent) and PA is the fuel polycyclic aromatic content (percent). According to Clark [40] an appropriate value of m for the Naegeli-Moses data would be 0.055. where N is the naphthalene content It is of interest to note that Rosfjord considered the quality of this correlation to be "equal to that for a smoke point correlation, both of which are superior to a solely hydrogen content correlation.

The influence of fuel composition on soot emissions from continuous flow combustors is examined. A study of the combustion characteristics of a wide range of present and potential aviation fuels suggests that smoke point provides a better indication of sooting tendency than does hydrogen content. It is concluded from this study that the best empirical relationship between fuel chemical composition and soot emissions is one which combines two fuel composition parameters — smoke point and naphthalene content — into a single parameter which is shown to correlate successfully soot emissions data acquired from several different fuels burning in a variety of gas turbine and model combustors.

“…In recent years, hydrogen content has been proposed as a better predictor of the sooting tendency of aviation fuels (Blazowski, 1979;Naegeli and Moses, 1980;Bowden, et al, 1984). Also, total aromatic content of the fuel, and polycyclic aromatic content have been used by some investigators to describe the soot radiation in combustors (Clark, 1984;Rosfjord, 1984). Each of these available sooting tendency predictors is being widely criticized because non of them are fully capable of describing the soot radiation encountered in gas turbine combustors.…”

A systematic study of soot formation along the centerlines of axisymmetric laminar diffusion flames of a large number of liquid hydrocarbons, hydrocarbon blends, and aviation turbine and diesel fuels was made. Measurements of the attenuation of a laser beam across the flame diameter were used to obtain the soot volume fraction, assuming Rayleigh extinction. Two sets of hydrocarbon blends were designed such that the molecular fuel composition varied considerably but the temperature fields in the flames were kept practically constant. Thus it was possible to separate the effects of molecular structure and the flame temperature on soot formation. It was quantitatively shown that the smoke point height is a lumped measure of fuel molecular constitution. The developed empirical relationship between soot volume fractions and fuel smoke point and hydrogen-to-carbon ratio was applied to five different combustor radiation data, and good agreement was obtained.
