Dispersity characteristics of methanol-diesel oil emulsified fuel

The disperse phase (methanol) droplet size of emulsified fuel has a significant effects on the combustion methanol-diesel oil emulsified fuel. The methanol droplet sauter mean diameter in methanol-diesel oil emulsified fuel was characterized with microphotography and arithmetic statistic method. Effects of rotor speed of disperser, emulsified time, additive amount and methanol content on the dispersity characteristics were investigated. The experimental results showed that the disperse phase (methanol) droplet size of emulsified fuel decreased with the augment of the rotor speed and additive amount, and almost contrary to the methanol content. The disperse becomes much better when emulsified time is 2min, rotor speed is 5×2800r/min, additive amount is 5% and methanol content is 10%, whose mean diameter is 16μm under experimental condition.
