Shear-Induced Droplet Breakup and Subsequent Coalescence of the Daughter Droplets

TL;DR

This paper presents high-resolution GPU simulations of droplet breakup and coalescence in shear flow, revealing the transition from coalescence to sliding as capillary number increases.

Contribution

It provides detailed simulation data on droplet behavior in shear flow, highlighting the transition mechanisms at different capillary numbers.

Findings

Transition from coalescence to sliding with increasing capillary number

High-resolution GPU simulations capture detailed droplet dynamics

Identification of breakup and collision behaviors in shear flow

Abstract

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.
