Recent experimental investigations showed that ultra-dispersed powders of mechanically activated nanocomposite Al-MoO3 and Mg-MoO3 particles exhibit anaerobic explosion-type reaction at relatively small heating up to 500-600K. Therefore thickening of liquid hydrocarbons with such particles can be effectively used for mixture homogenization in transportation engines and decreasing pollutant emissions into the atmosphere. When placed into a hot gaseous flow, thickened-fuel drops can exhibit controlled ‘microexplosion’ behavior. In this paper, the possibility of thickened-fuel drop ‘microexplosion’ is examined using a mathematical model of single-component drop heating, evaporation, and combustion.
