| Summary: | Title screen With a variety of industrial applications involving the collisions of droplets and particles in gas, it is important to explore processes during their agglomeration and separation, as well as their classification. By recording the characteristics of droplet-particle interaction in aerosol flows, it will be possible to significantly optimize processes in abundance of systems for dust collection, liquid filtration, fine spraying, etc. The purpose of this research was to experimentally study the characteristics of interaction between water droplets and particles of coal and sand, when varying the ambient temperature from 25 to 300°С. A high-speed camera was employed to obtain shadow images of interaction of droplets and particles, with their respective velocities varying from 0.2 to 15.1 m/s and from 0.4 to 33.8 m/s. The obtained data were plotted as curves taking account of dimensionless numbers (the Weber, Reynolds, Froude and Stokes numbers). Predictive equations were derived on the basis of the experimental findings. With a temperature increase from 25°С to 300°С, the number of child droplets rose by almost 30 %. The interaction outcome was found to be mainly affected by the shape and size of solid particles, as well as their impact velocity Текстовый файл AM_Agreement |
