NEW EXPERIMENTAL DATA OF CHILD DROPLETS IDENTIFICATION AFTER TWO-LIQUID DROPLET BREAKUP
New experimental data of child droplets characteristics (times to puffing/microexplosion, distribution of sizes, and ratio of the evaporation surface area before and after puffing/microexplosion) of heated two-liquid droplets in puffing and microexplosion modes are presented. Different droplet configuration effects (fuel liquid (rapeseed oil) - shell, water-core, vice versa) are discussed. The experiments were carried out with two-liquid droplets in which coal particles were added to meet nonpremixed spray technologies into the combustion chambers. Breakup conditions of water/fuel droplets in monodisperse and polydisperse aerosols are determined. The difference in secondary atomization effects of water and fuel is described. The effect of gas temperature in the range 720-1070 K on child droplets characteristics is discussed.
