In order to explore the flame propagation mechanism of less-volatile fuel spray, flame propagation experiments of n-decane spray were performed in microgravity using JAMIC drop-shaft. Relationships between flame speed, SMD, and the equivalence ratio were investigated. Effects of a small quantity of methane addition and reduced oxygen concentration were also examined. Results showed that flame speed variations with SMD and equivalence ratio for various conditions in this experiment can be reasonably explained based on the analogy with the flame spread phenomenon of a droplet array for less-volatile fuel. That is, flame speed has the maximum when the mean droplet spacing estimated based on volumetric mean droplet diameter is closest to the flame radius of a single droplet.
