Shear-Induced Droplet Breakup and Subsequent Coalescence of the Daughter   Droplets
  In this fluid dynamics video we show simulations of droplet breakup and collisions in simple shear flow. Due to the high resolution of the GPU-based simulations, we capture the transition from coalescence at low capillary numbers to sliding at higher values.
