The influence of hydrogen addition on the burning rates of kerosene sprays in air is studies experimentally. Flame speeds are measured as a function of fuel drop size, equivalence ratio, and hydrogen concentration. The results obtained show that evaporation rates have a controlling effect on flame speeds over wide ranges of mean drop size. They also demonstrate that the burning rates of liquid kerosene air mixtures are augmented appreciably by the addition of small quantities of hydrogen to the air flowing into the combustion zone.
