摘要：The micro-explosion phenomenon of emulsified fuel when heated is known to improve thermal effi-ciency of combustion and reduce pollutant emissions. In this study, a new methodology is developed to evaluate the intensity and atomization effect of micro-explosion on a model droplet volume. The micro-explosion phenomenon of water-in-oil emulsified fuels prepared with different surfactants was studied using a single droplet micro-explosion shadow-imaging apparatus, and the proposed evaluation methods were verified. The results show that this new method can accurately predict the intensity and atomization effect of a single droplet undergoing micro-explosion. In addition, the addition of water-soluble surfactants effectively improves the intensity and atomization effect of the micro-explosion phe-nomenon in heterogeneous nucleation.(c) 2022 Elsevier Ltd.
