Measurements of soot concentration and soot mass were performed in microgravity conditions for hexane, heptane, nonane, and decane droplets burning in air at the NASA Glenn Research Center (GRC) 2.2 s drop tower in Cleveland, OH. Experiments performed in air at 75.9 and 101.3 kPa indicate that the maximum soot Volume fractions and soot mass are similar, to within experimental uncertainty, for all of the fuels tested. The flame standoff ratios (FSR) did not vary significantly for the fuels considered. The soot standoff ratio for decane was significantly smaller than For the other fuels.
