    The effect of hydrogen addition on silica growth in burner-stabilized methane/air flames with trace amounts of hexamethyldisiloxane are reported. Profiles of the aggregates' radius of gyration R-g and monomer radius a versus residence time were measured by laser light scattering. Experiments were performed at equivalence ratios of 0.8, 1.0 and 1.3, with mole fractions of 0-0.4 of hydrogen in the fuel. At equal mass flux, the addition of hydrogen was found to result in decreasing R-g and a. However, keeping the flame temperature rather than the mass flux constant upon hydrogen addition resulted in the same measured profiles. (C) 2017 Hydrogen Energy Publications LLC.
