Flame Speeds in Fuel Sprays With Hydrogen Addition

The influence of hydrogen addition on the burning rates of kerosine sprays in air is studied 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 s...

Description
Summary:The influence of hydrogen addition on the burning rates of kerosine sprays in air is studied 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 kerosine-air mixtures are augmented appreciably by the addition of small quantities of hydrogen to the air flowing into the combustion zone.
