The analysis of the effect of emulsifier properties on the breakup characteristics of fuel microemulsion (FME) droplets heated on a heated surface was carried out using such co-surfactants as nonanol-1, 2-ethylhexanol and isomyl alcohol with carbon chain lengths of 9, 8, and 5, respectively. The effect of the particle (microdroplets) size of the dispersed phase on the temporal characteristics of vaporization and explosive breakup of FME droplets in experiments with conductive heating was examined. A physical description of vaporization and explosive breakup of FME droplets during conductive heating was performed. The minimum film boiling temperatures of FME droplets were determined. The results will be useful in the creation of new water-in-diesel microemulsions, as well as in the development of technologies for the secondary atomization of such fuels in the combustion chambers of engines and power plants.
