This paper reviews recent advances in droplet vaporization and combustion in three areas; namely (1) the gasification mechanisms of multicomponent droplets, in which the authors show that while liquid-phase diffusional resistance is very strong for the immiscible emulsion systems, it is only moderately effective for miscible mixtures such that their gasification mechanism is intermediate of those of batch distillation and diffusion-limited steady state; (2) the role of water and alcohol addition in the soot formation from droplet burning, in which the authors show dilution and thermal effects are primarily responsible for the observed soot reduction while the presence of the hydroxyl group has no effect; and (3) the gasification of droplets or organic azides, in which the authors show that they have extremely rapid gasification rates as well as a greater propensity to micro-explode due to the occurrence of liquid-phase reaction.
