Droplets bouncing over a vibrating fluid layer

TL;DR

This paper presents visualizations of levitated liquid droplets over a vibrating fluid layer, exploring their motion, cluster formation, and stability through fluid dynamics videos.

Contribution

It provides detailed visual analysis of droplet behavior on a vibrating fluid surface, highlighting cluster formation and stability, which is a novel visualization approach.

Findings

Droplets can be levitated by vertical vibration.

Clusters of droplets form and exhibit stability.

Visualizations reveal dynamic droplet interactions.

Abstract

This is an entry for the Gallery of Fluid Motion of the 65st Annual Meeting of the APS-DFD (fluid dynamics video). This video shows the motion of levitated liquid droplets. The levitation is produced by the vertical vibration of a liquid container. We made visualizations of the motion of many droplets to study the formation of clusters and their stability.
