Effect of shear on droplets in a binary mixture

TL;DR

This study uses lattice-Boltzmann simulations to explore how shear flow influences droplet behavior in binary mixtures, revealing breakup, dissolution, and dynamic equilibrium phenomena.

Contribution

It provides new insights into droplet dynamics under shear in binary mixtures using detailed lattice-Boltzmann simulations.

Findings

Large drops break up with increased shear

Small drops dissolve under shear

Tip-streaming leads to dynamic equilibrium

Abstract

In this article 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.
