The short life of a droplet

TL;DR

This paper explores how the sediment geometry of a drying water droplet with suspended particles relates to the internal fluid dynamics during drying, providing insights into the drying process and sediment formation.

Contribution

It introduces a correlation between sediment geometry and internal fluid dynamics in drying droplets, offering a novel perspective on drying behavior and sediment patterns.

Findings

Sediment geometry correlates with internal fluid flow.

Drying dynamics influence sediment distribution.

Insights into drying processes of particle-laden droplets.

Abstract

This is the companion paper of the Fluid Dynamics Video "The short life of a drop" where it is argued that the geometry of the sediment of a drop of water with particles in suspension can be correlated with the dynamics of the fluid inside the drop during the drying process.
