✦ Synopsis

An experimental study has been made to measure the size and the concentration profile of soot in a flame formed around a suspended fuel droplet by using a laser light scattering technique. The results indicate that the heavily sooting region is located fairly close to the droplet surface inside the high temperature region. Adding ethanol or n-heptane to benzene has a definite effect on reducing soot in the droplet flame. This also causes the heavily sooting region to shift slightly toward the droplet surface while the temperature profile remains unchanged. It is also indicated that the maximum soot concentration in the droplet flame increases with the increase in the C/H ratio of the fuels tested.
