Summary:This research aims to identify patterns and study the characteristics of secondary atomization of fuel oil/water emulsion droplets containing specialized additives (R503V3 0.5 %, R502V1 0.5 %, and ION M 0.5 %). The ION M additive was able to increase the number of secondary fragments by 10–25 % with typical sizes of about 0.05 mm. The results showed that the use of specialized additives based on fatty acids of vegetable oils (compositions No. 3 and 4) and on a particular combination of positively and negatively charged ions (composition No. 5) with the fuel increased the efficiency of micro-explosive atomization by 28.4 %, 43.4 % and 59.8 %, respectively. With the additive based on a particular combination of positively and negatively charged ions in a fuel oil/water emulsion, the implementation of 4 technologies secondary atomization results in an almost 240-fold increase in the free surface area of droplets at a Weber number of 125. Such increase in the free surface area of droplets leads to more complete combustion of the fuel due to a larger total area of vaporization and combustion. Approximation equations were derived to predict the conditions of consistent occurrence of droplet fragmentation in all the secondary atomization regimes.
