Zusammenfassung:Title screen
The experimental research into water droplet collisions resulting in their secondary atomization has been performed. The temperature of the first and second droplets was 20°С and 90°С, respectively. The interaction regime maps using the dimensionless linear collision parameter and the Weber number have been plotted. We also determined the integral characteristics of child droplets: size and number. When droplets with a temperature of 90°С were used, the critical Weber numbers went down by 10–30% for disruption, 5–15% for separation, and 15–35% for coalescence. For bounce, they increased by 50–80%. The number of newly formed child droplets for droplets with a temperature of 90°С increased by 5–20% relative to the droplets with a temperature of 20°С. The integral characteristics of child droplets and interaction regime maps of droplets with different temperatures can be used to optimize heat and mass transfer technologies.
