| Özet: | Title screen This article presents the research findings on binary collisions of water droplets and solid particles using three most widely spread ranks of coal. The experimental setup used in this research allowed the variation of the particle size from 0.25 mm to 0.75 mm and the velocity from 0.5 m/s to 4 m/s. The droplet velocity was varied from 0.3 m/s to 6 m/s. The impact angle of attack ranged 0-90°. These variation ranges of initial parameters correspond to promising gas-vapor-droplet technologies such as spray drying, fire extinguishing, water treatment, fuel mixing and combustion, heat and mass transfer power plants, etc. We analyzed the frames showing three collision regimes: coalescence, separation, and disruption. We determined how the temperature of the liquid medium affects the position of droplet collision regime boundaries on the corresponding maps in the B(We) coordinates. We also determined the impact of hydrophilic and hydrophobic behavior of solid particles on the collision characteristics. The size distributions were established for secondary fragments formed during the collision of water droplet and solid particle, as well as the collision of two droplets. The key patterns of the processes under study were singled out for various droplet shapes and size ratios. Finally, we compared the characteristics and conditions of interaction between water droplets and water-based slurries. Режим доступа: по договору с организацией-держателем ресурса |
