Summary:Title screen
The relevance of the study is due to the necessity to intensify the secondary atomization of fuel droplets by their collisions with each other. The indispensable conditions for sustainable implementation of each of four collision regimes (coalescence, bouncing, separation and disruption) have been established. The experiments were carried out by varying the group of governing parameters in wide ranges: velocity of each droplet (0.5–5?m/s), its dimensions (0.1–5?mm) and angles of attack (0–90°), density (900–1150?kg/m3), viscosity (0.0001–0.5?Pa•s), surface tension (0.01–0.25?N/m), component composition of fuels (slurries and emulsions), degree of solid particle fineness (40–140?µm), and initial temperature (20–80?°C). The ranges of the main parameters in the dimensional and dimensionless coordinate systems providing conditions for intense droplet disruption have been defined. The most valuable experimental results are the determined conditions for a multiple increase in the number of child-droplets.
