The Effect of Shear on Droplets in a Binary Mixture — •Alexander J. Wagner and J.M Yeomans — Theoretical Physics, University of Oxford, 1 Keble rd., GB.

We use a lattice-Boltzmann simulation to examine the effects of shear flow on a equilibrium droplet in a phase separated binary mixture. We find that large drops break up as the shear is increased but small drops dissolve. We also show how the tip-streaming, observed for deformed drops, leads to a state of dynamic equilibrium.
