Fragmentation of Falling Liquid Droplets in Bag Breakup Mode

A droplet is followed in free-fall as it breaks-up, at three different Eo numbers: 144, 288, 303.

Kelvin-Helmholtz and Rayleigh-Taylor instabilities on a Droplet

The initiation and growth of instabilities on a droplet at Re=22,000 and We=100 is carefully followed and compared with linear instability analyses.
