WebApr 15, 2024 · Two regions of drop breakup were outlined: inside and outside the impeller-disc edge. In the impeller-disc edge region, the dispersed drop was always elongated in the direction of the drop motion. However, outside the disc-edge region, the dispersed drop was elongated in random directions, independent of the drop’s motion.
