| Izvleček: | Title screen It is important to understand the physics of liquid droplet collisions for a variety of applications ranging from inkjet printing to composite fuel combustion. The use of composite fuels is associated with some challenges and limitations. It is necessary to study the collisions of droplets and particles used as slurry fuel components. The selected objects of research were water and oil droplets, as well as particles of pine, cedar, coal and filter cake. Typical collision regimes (agglomeration and destruction) were identified. The characteristics of child droplets and conditions of their interaction with droplets and particles were determined. Differences between the characteristics of interaction of combustible and noncombustible component droplets with particles were detected. Equations were presented for a mathematical description of transition boundaries between regimes on maps taking account of the dimensionless linear impact parameter, the Weber number and the Ohnesorge number. The decisive factor for agglomeration or separation of droplets and particles was the properties of liquid. If a particle was pre-wetted, the type and condition of its surface did not have a significant effect on interaction regimes. The occurrence of a regime was also found to depend on the particle shape. A comparison of interaction regime maps for liquid droplets and biomass particles in the experiments with water and motor oil revealed that the separation boundary for oil shifted towards 18–27 % higher Weber numbers. This is accounted for by the physical properties of the investigated liquids. Guidelines on using the research findings in the development of secondary atomization technologies of fuel droplets were provided Текстовый файл AM_Agreement |
