Question

How does droplet atomization influence flame behaviour

Answer 1

Solution

Thus, it is important to understand the influence of distinct atomization modes prevalent at different proportions of volatile component on the flame disruptive behavior. Based on the augmentation in the severeness of droplet deformation. the bubble breakup events can be referred to as low-intensity minor breakups (Mode 1); intermediate intensity breakups (Mode 2); high-intensity major breakups (Mode 3); and micro-explosions (Mode 4). A minor breakup event usually indicates ejection of small-sized secondary droplets, which initiates small-scale surface roughening and moderate oscillations in droplet volume. Similarly, a major breakup event indicates major bubble collapse event that corresponds to the breakup of a substantial bubble volume leading to severe droplet deformation. Besides, the parent droplet may not recover from the high degree of deformation induced by the fragmentation of a significantly large bubble leading to micro-explosion.
