| সংক্ষিপ্ত: | Title screen Understanding the specific aspects of binary interactions of coal-water slurry droplets is crucial for optimizing the transportation of this fuel and spraying in industrial applications. This research presents experimental findings for binary collisions of coal-water slurry droplets, when varying the ambient air temperature (from 25 to 200°C), concentration of solid coal particles (from 0.5 to 5%), and geometry of collisions. Using high-speed video recording, the following interaction regimes of droplets were recorded: bounce, coalescence, reflexive separation, and stretching separation. Droplet interaction regime maps were plotted to identify the boundaries between regimes depending on the solid phase concentration in the slurry and ambient temperature. The probability of occurrence of a regime was not significantly dependent on the coal concentration in the slurry in the considered range, but was very sensitive to the impact angle and velocity. It was hypothesized that the geometry of the lamella forming in off-center interaction determines the number of secondary fragments (child droplets) after its breakup. The inertial forces of droplets and thermophysical properties of the gas medium rather than the solid phase concentration in the liquid have a decisive effect on the droplet interaction outcome Текстовый файл AM_Agreement |
